Description

The TS93x (single, dual & quad) series are operational amplifiers able to operate with voltage as low as 2.7V and to reach 2.9Vpp of output swing with R

Offering a typical consumption of only 20 are particularly well-suited for battery-powered applications.

Fitting the TS93x o nto your board design is very easy because of its space-saving 5-pin SOT23-5 package with outer dimensions of

2.8mm x 2.9mm.
