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.
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).
