The TL97x family of single, dual, and quad operational amplifiers operates at voltages as low as ±1.35 V and features output rail-to-rail signal swing. The TL97x boasts 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 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).
