3 Description
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 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 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).
