Description
TS922 and TS922A devices are rail-to-rail dual
BiCMOS operational amplifiers optimized and
fully specified for 3 V and 5 V operation. These
devices have high output currents which allow
low-load impedances to be driven.
Very low noise, low distortion, low offset, and
a high output current capability make these
devices an excellent choice for high quality, low
voltage, or battery operated audio systems.
The devices are stable for capacitive loads up to
500 pF.

1. All voltage values, except differential voltage are with respect to network ground terminal.
2. The differential voltage is the non-inverting input terminal with respect to the inverting input terminal. If
V
id
> ±1 V, the maximum input current must not exceed ±1 mA. In this case (V
id
> ±1 V), an input series
resistor must be added to limit the input current.
3. Do not exceed 14 V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-
circuits on all amplifiers. These values are typical.
5. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5
Ω).
This is done for all couples of
pin combinations with other pins floating.
7. Charged device model: all pins and plus package are charged together to the specified voltage and then
discharged directly to ground.
8. There is no short-circuit protection inside the device: short-circuits from the output to V
CC
can cause
excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of
V
CC
. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
