DESCRIPTION

OPA336 series micropower CMOS operational ampli­fiers are designed for battery powered applications.
They operate on a single supply with operation as low
as 2.1V. The output is rail-to-rail and swings to within
3mV of the supplies with a 100kΩ load. The common­mode range extends to the negative supply—ideal for
single-supply applications. Single, dual, and quad
versions have identical specifications for maximum
design flexibility.

In addition to small size and low quiescent current
(20µA/amplifier), they feature low offset voltage
(125µV max), low input bias current (1pA), and high
open-loop gain (115dB). Dual and quad designs fea­ture completely independent circuitry for lowest
crosstalk and freedom from interaction.

OPA336 packages are the tiny 5-lead SOT-23-5 surface
mount, SO-8 surface-mount, and 8-pin DIP. OPA2336
comes in the miniature MSOP-8 surface-mount, SO-8
surface-mount, and 8-pin DIP packages. OPA4336
packages are the space-saving SSOP-16 surface-mount
and the 14-pin DIP. All are specified from –40°C to
+85°C and operate from –55°C to +125°C. A
macromodel is available for design analysis.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

APPLICATIONS INFORMATION

OPA336 series op amps are fabricated on a state-of-the-art

0.6 micron CMOS process. They are unity-gain stable and
suitable for a wide range of general purpose applications.
Power supply pins should be bypassed with 0.01µF ceramic
capacitors. OPA336 series op amps are protected against
reverse battery voltages.

OPERATING VOLTAGE

OPA336 series op amps can operate from a +2.1V to +5.5V
single supply with excellent performance. Most behavior
remains unchanged throughout the full operating voltage
range. Parameters which vary significantly with operating
voltage are shown in the typical performance curves. OPA336
series op amps are fully specified for operation from +2.3V
to +5.5V; a single limit applies over the supply range. In
addition, many parameters are guaranteed over the specified
temperature range, –40°C to +85°C.

INPUT VOLTAGE

The input common-mode range of OPA336 series op amps
extends from (V–) –0.2V to (V+) –1V. For normal opera­tion, inputs should be limited to this range. The absolute
maximum input voltage is 300mV beyond the supplies.
Thus, inputs greater than the input common-mode range
but less than maximum input voltage, while not valid, will
not cause any damage to the op amp. Furthermore, the
inputs may go beyond the power supplies without phase
inversion (Figure 1) unlike some other op amps.

CAPACITIVE LOAD AND STABILITY

OPA336 series op amps can drive a wide range of capaci­tive loads. However, all op amps under certain conditions
may become unstable. Op amp configuration, gain, and
load value are just a few of the factors to consider when
determining stability.

When properly configured, OPA336 series op amps can
drive approximately 10,000pF. An op amp in unity gain
configuration is the most vulnerable to capacitive load. The
capacitive load reacts with the op amp’s output resistance,
along with any additional load resistance, to create a pole in
the response which degrades the phase margin. In unity gain,
OPA336 series op amps perform well with a pure capacitive
load up to about 300pF. Increasing gain enhances the
amplifier’s ability to drive loads beyond this level.

One method of improving capacitive load drive in the unity
gain configuration is to insert a 50Ω to 100Ω resistor inside
the feedback loop as shown in Figure 3. This reduces ringing
with large capacitive loads while maintaining DC accuracy.

FIGURE 1. No Phase Inversion with Inputs Greater than the

Power Supply Voltage.

Normally, input bias current is approximately 1pA. How­ever, input voltages exceeding the power supplies can
cause excessive current to flow in or out of the input pins.
Momentary voltages greater than the power supply can be
tolerated as long as the current on the input pins is limited
to 10mA. This is easily accomplished with an input resis­tor as shown in Figure 2.

For example, with RL = 25kΩ, OPA336 series op amps
perform well with capacitive loads in excess of 1000pF
(Figure 4). Without RS, capacitive load drive is typically
350pF for these conditions (see Figure 5).

Alternatively, the resistor may be connected in series with
the output outside of the feedback loop. However, if there is
a resistive load parallel to the capacitive load, it and the
series resistor create a voltage divider. This introduces a DC
error at the output. However, this error may be insignificant.
For instance, with R

= 100kΩ and RS = 100Ω, there is only

L

about a 0.1% error at the output.
Figure 5 shows the recommended operating regions for the

OPA336. Decreasing the load resistance generally improves
capacitive load drive. Figure 5 also illustrates how stability
differs depending on where the resistive load is connected.
With G = +1 and R

= 10kΩ connected to VS/2, the OPA336

L

can typically drive 500pF. Connecting the same load to
ground improves capacitive load drive to 1000pF.
