Description
The TS97x family of operational amplifiers
operate with voltages as low as ±1.35 V and
feature output rail-to-rail signal swing. The TS97x
devices 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 TS97x devices are available in a variety of
packages to suit all types of applications. For
applications where space saving is critical, the
SOT23-5 package (2.8 x 2.9 mm) or the DFN8
package (3 x 3 mm) simplify the board design
because they can be placed anywhere on it.

Human
body model: a 100 pF 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 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 floating.
(7)
No value specified for CDM on SOT23-5 package.
(8)
Charged
device model: all pins and package are charged together to the specified voltage and then discharged
directly to ground through only one pin. This is done for all pins.
