The MC33102 dual operational amplifier is an innovative design concept
employing Sleep–Mode technology. Sleep–Mode amplifiers have two
separate states, a sleepmode and an awakemode. In sleepmode, the
amplifier is active and waiting for an input signal. When a signal is applied
causing the amplifier to source or sink 160 µA (typically) to the load, it will
automatically switch to the awakemode which offers higher slew rate, gain
bandwidth, and drive capability.

• Two States: “Sleepmode” (Micropower) and “Awakemode”

(High Performance)

• Switches from Sleepmode to Awakemode in 4.0 µs when Output Current

Exceeds the Threshold Current (RL = 600 Ω)

• Independent Sleepmode Function for Each Op Amp

• Standard Pinouts – No Additional Pins or Components Required

• Sleepmode State – Can Be Used in the Low Current Idle State as a

Fully Functional Micropower Amplifier

• Automatic Return to Sleepmode when Output Current Drops Below

Threshold

• No Deadband/Crossover Distortion; as Low as 1.0 Hz in the Awakemode

• Drop–in Replacement for Many Other Dual Op Amps

• ESD Clamps on Inputs Increase Reliability without Affecting Device

Operation

Sleep–Mode is a trademark of Motorola, Inc.

CIRCUIT INFORMATION

The MC33102 was designed primarily for applications
where high performance (which requires higher current drain)
is required only part of the time. The two–state feature of this
op amp enables it to conserve power during idle times, yet be
powered up and ready for an input signal. Possible
applications include laptop computers, automotive, cordless
phones, baby monitors, and battery operated test equipment.
Although most applications will require low power
consumption, this device can be used in any application
where better efficiency and higher performance is needed.

The Sleep–Mode amplifier has two states; a sleepmode
and an awakemode. In the sleepmode state, the amplifier is
active and functions as a typical micropower op amp. When a
signal is applied to the amplifier causing it to source or sink
sufficient current (see Figure 13), the amplifier will
automatically switch to the awakemode. See Figures 20 and
21 for transition times with 600 Ω and 10 kΩ loads.

The awakemode uses higher drain current to provide a
high slew rate, gain bandwidth, and output current capability .
In the awakemode, this amplifier can drive 27 Vpp into a
600 Ω load with VS = ±15 V.

An internal delay circuit is used to prevent the amplifier
from returning to the sleepmode at every zero crossing. This
delay circuit also eliminates the crossover distortion
commonly found in micropower amplifiers. This amplifier can
process frequencies as low as 1.0 Hz without the amplifier
returning to sleepmode, depending on the load.

The first stage PNP differential amplifier provides low noise
performance in both the sleep and awake modes, and an all
NPN output stage provides symmetrical source and sink AC
frequency response.

APPLICATIONS INFORMATION

The MC33102 will begin to function at power supply
voltages as low as VS = ±1.0 V at room temperature. (At this
voltage, the output voltage swing will be limited to a few
hundred millivolts.) The input voltages must range between
VCC and VEE supply voltages as shown in the maximum
rating table. Specifically, allowing the input to go more

negative than 0.3 V below VEE may cause product
damage. Also, exceeding the input common mode voltage

range on either input may cause phase reversal, even if the
inputs are between VCC and VEE.

When power is initially applied, the part may start to
operate in the awakemode. This is because of the currents
generated due to charging of internal capacitors. When this
occurs and the sleepmode state is desired, the user will have
to wait approximately 1.5 seconds before the device will
switch back to the sleepmode. T o prevent this from occurring,
ramp the power supplies from 1.0 V to full supply. Notice that
the device is more prone to switch into the awakemode when
VEE is adjusted than with a similar change in VCC.

The amplifier is designed to switch from sleepmode to
awakemode whenever the output current exceeds a preset

current threshold (ITH) of approximately 160 µA. As a result,
the output switching threshold voltage (VST) is controlled by
the output loading resistance (RL). This loading can be a load
resistor, feedback resistors, or both. Then:

VST = (160 µA) × R

L

Large valued load resistors require a large output voltage
to switch, but reduce unwanted transitions to the
awakemode. For instance, in cases where the amplifier is
connected with a large closed loop gain (ACL), the input offset
voltage (VIO) is multiplied by the gain at the output and could
produce an output voltage exceeding VST with no input
signal applied.

Small values of RL allow rapid transition to the awakemode
because most of the transition time is consumed slewing in
the sleepmode until VST is reached (see Figures 20, 21). The
output switching threshold voltage VST is higher for larger
values of RL, requiring the amplifier to slew longer in the
slower sleepmode state before switching to the awakemode.

Where:

Although typically 160 µA, ITH varies with supply voltage
and temperature. In general, any current loading on the
output which causes a current greater than ITH to flow will
switch the amplifier into the awakemode. This includes
transition currents such as those generated by charging load
capacitances. In fact, the maximum capacitance that can be
driven while attempting to remain in the sleepmode is
approximately 1000 pF.

= 160 µA/(0.16 V/µs)

Any electrical noise seen at the output of the MC33102

may also cause the device to transition to the awakemode. T o

minimize this problem, a resistor may be added in series with
the output of the device (inserted as close to the device as
possible) to isolate the op amp from both parasitic and load
capacitance.

The awakemode to sleepmode transition time is controlled
by an internal delay circuit, which is necessary to prevent the
amplifier from going to sleep during every zero crossing. This
time is a function of supply voltage and temperature as
shown in Figure 22.

Gain bandwidth product (GBW) in both modes is an
important system design consideration when using a
sleepmode amplifier. The amplifier has been designed to
obtain the maximum GBW in both modes. “Smooth” AC
transitions between modes with no noticeable change in the
amplitude of the output voltage waveform will occur as long
as the closed loop gains (ACL) in both modes are
substantially equal at the frequency of operation. For smooth
AC transitions:

TESTING INFORMATION

To determine if the MC33102 is in the awakemode or the
sleepmode, the power supply currents (ID+ and ID–) must be
measured. When the magnitude of either power supply
current exceeds 400 µA, the device is in the awakemode.
When the magnitudes of both supply currents are less than
400 µA, the device is in the sleepmode. Since the total supply
current is typically ten times higher in the awakemode than
the sleepmode, the two states are easily distinguishable.

The measured value of ID+ equals the ID of both devices
(for a dual op amp) plus the output source current of device A
and the output source current of device B. Similarly, the
measured value of ID– is equal to the ID– of both devices plus
the output sink current of each device. I

out

is the sum

of the currents caused by both the feedback loop and load
resistance. The total I

out

needs to be subtracted from the

measured ID to obtain the correct ID of the dual op amp.

An accurate way to measure the awakemode I

out

current

on automatic test equipment is to remove the I

out

current on
both Channel A and B. Then measure the ID values before
the device goes back to the sleepmode state. The transition
will take typically 1.5 seconds with ±15 V power supplies.

The large signal sleepmode testing in the characterization
was accomplished with a 1.0 MΩ load resistor which ensured
the device would remain in sleepmode despite large
voltage swings.
