Description
TS972IQT (DFN8)
The TS97x family of operational amplifiers
operates with voltages as low as ±1.35V and
features output rail-to-rail signal swing. The
TS97x are particularly well suited for portable and
battery-supplied equipment. Very low noise and
low distortion characteristics make them ideal for
audio pre-amplification.

The TS971 is available in a variety of packages to
suit all types of applications. For applications
where space-saving is critical, the SOT23
package (2.8 x 2.9mm) or the DFN package
(3 x 3mm) simplify the board design because they
can be placed everywhere.

1. All voltage values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed VCC +0.3V.
4. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
7. 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.
No value specified for CDM on SOT23-5 package.
