Applications Information

1. Input Common Mode Range and Output
Voltage Considerations

The CMV1010 is capable of accommodating an input
common mode voltage equal to one volt below the
positive rail and all the way to the negative rail. It is
also capable of output voltages equal to both power
supply rails. Voltages that exceed the supply voltages
will not cause phase inversion of the output, however,
ESD diode clamps are provided at the inputs that can
be damaged if static currents in excess of ±5mA are
allowed to flow in them. This can occur when the
magnitude of input voltage exceeds the rail by more
than 0.3 volt. To preclude damage, an applications
resistor, R
as illustrated in Figure 1 whose value for R

supply voltage in split rail applications. Since device
only draws 60µA supply current (100µA maximum), its
contribution to the junction temperature, T

, is negli-

gible. As an example, let us analyze a situation in
which the CMV1010 is operated from a 5 volt supply
and ground, the output is “programmed” to positive
saturation, and the output pin is indefinitely shorted to
ground. In general:

The contribution to power dissipation due to supply

above.

The primary contribution to power dissipation occurs in

2. Output Current and Power Dissipation

Considerations

The CMV1010 is capable of sinking and sourcing
output currents in excess of 7mA at voltages very
nearly equal to the rails. As such, it does not have any
internal short circuit protection (which would in any
event detract from its rail to rail capability). Although
the power dissipation and junction temperature rise are
small, a short analysis is worth investigating.

Obviously, the worst case from a power dissipation
point of view is when the output is shorted to either
ground in a single rail application or to the opposite

The SOT23 exhibits a θ

equal to 325°C/W. Thus for

JA

our example the junction rise would be about 11.4
which is clearly not a destructive situation even under
an ambient temperature of 85°C.

3. Input Impedance Considerations

The CMV1010 exhibits an input impedance typically in
excess of 1 Tera Ω (1 X 10
appropriate for applications involving high source
impedance such as photodiodes and high output
impedance transducers or long time constant integra­tors. High source impedances usually dictate large
feedback resistors. But, the output capacitance of the
source in parallel with the input capacitance of the
CMV1010 (which is typically 3pF) create a parasitic
pole with the feedback resistor which erodes the
phase margin of the amplifier. The usual fix is to
bypass, R

, as shown in Figure 2 with a small capaci-

calculating C

always results in a value larger than that

perfected by TV technicians in the 1950’s. A gimmick
is made by taking two lengths (typically about a foot)
of small gauge wire such as AWG24, twisting them
together, and then after baring all ends soldering the
gimmick across R

. With the circuit operating, CF is

"adjusted" by clipping short lengths of the gimmick off
until the compensation is nominal. Then simply
remove the gimmick, take it to an impedance bridge,
and select the capacitor accordingly.

Operational amplifiers have been used for years to
generate frequency stable oscillators, but the circuit

4. Capacitive Load Considerations

The CMV1010 is capable of driving capacative loads
in excess of 100pF without oscillation. However,
significant peaking will result. Probably the easiest
way minimize this problem is to use an isolation
resistor as shown in Figure 3.

Figure 3

5. Power Supply Decoupling

The CMV1010 is not prone to oscillation without the
use of power supply decoupling capacitors, however to
minimize hum and noise pick-up, it is recommended
that the rails be bypassed with 0.01µF capacitors.

Figure 4

Personal Computers including laptops are available
with sophisticated and high quality audio capabilities.
Battery conservation is a key issue with laptop
computers, and the circuit in Figure 5 utilizes the low
supply current of the CMV1010, its rail to rail output
voltage swing, and its high output current drive to
provide the interface to the microphone input. A
