8.1 Overview
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.
The TL97x family comes in single, dual, and quad operational amplifier packages of varying sizes.
The TL971 is housed in the space-saving 5-pin SOT-23 package, which simplifies board design because of the
ability to be placed anywhere (outside dimensions are 2.8 mm × 2.9 mm).

8.3 Feature Description
8.3.1 Slew Rate
The slew rate is the rate at which an operational amplifier can change its output when there is a change on the
input. The TL97x devices have a 5 V/μs slew rate.
8.3.2 Unity-Gain Bandwidth
The unity-gain bandwidth is the frequency up to which an amplifier with a unity gain may be operated without
greatly distorting the signal. The TL97x devices have a 12-MHz unity-gain bandwidth.
