DESCRIPTION

The TS97x family operational amplifiers is able to

operate with voltages as low as

±1.35V and featur-

ing output Rail to Rail signal swing. The TS97x

boasts characteristics that make them particularly

well suited for portable and battery-supplied equip-

ment. Very low noise and low distortion charac-

The TS971 is housed in the space-saving 5 pins

SOT23 package which simplifies the board design

because of the ability to be placed everywhere

(outside dimensions are 2.8mm x 2.9mm)
