DESCRIPTION/ORDERING INFORMATION
The TL97x family of operational amplifiers operates at voltages as low as ±1.35 V and features output rail-to-rail
signal swing. The TL97x boast characteristics that make them particularly well suited for portable and battery-
supplied equipment. Very low noise and low distortion characteristics make them ideal for audio preamplification.
