Description
The TS97x family of operational amplifiers
operates with voltages as low as ±1.35V and
features output rail-to-rail signal swing. The
TS97x are particularly well suited for portable and
battery-supplied equipment. Very low noise and
low distortion characteristics make them ideal for
audio pre-amplification.
The TS971 is available in a variety of packages to
suit all types of applications. For applications
where space-saving is critical, the SOT23
package (2.8 x 2.9mm) or the DFN package
(3 x 3mm) simplify the board design because they
can be placed everywhere.
