TS982
Wide bandwidth, dual bipolar operational amplifier
Datasheet - production data
Description
The TS982 device is a dual operational amplifier
able to drive 200 mA down to voltages as low as
2.7 V.
The SO-8 exposed-pad package allows high
current output at high ambient temperatures
making it a reliable solution for automotive and
industrial applications.

1. All voltage values are measured with respect to the ground pin.
2. With two sides, two-plane PCB following the EIA/JEDEC JESD51-7 standard.
3. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩresistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are left floating.
4. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
5. 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
connected pin combinations while the other pins are left floating.
6. Short-circuits can cause excessive heating. Destructive dissipation can result from a short-circuit on one or
two amplifiers simultaneously.
