Description

The TS507 is a high performance rail-to-rail input

and output amplifier with very low offset voltage.

This amplifier uses a new trimming technique that

yields ultra low offset voltages without any need

for external zeroing.

The circuit offers very stable electrical

characteristics over the entire supply voltage

range, and is particularly intended for automotive

and industrial applications.

The TS507 is housed in the space-saving 5-pin

SOT23 package, making it well suited for battery-

powered systems. This micropackage simplifies

the PC board design because of its ability to be

placed in tight spaces (external dimensions are

2.8 mm x 2.9 mm).
