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).
