Description

The TS507 is a high performance rail-to-rail

input/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 small spaces (external dimensions are

2.8

mm x 2.9 mm).

TS507 Application note 3 Application note The application note AN2653, based on the TS507, describes three compensation techniques for solving stability issues when driving large capacitive loads. Two of these techniques are briefly explained below. For more details, refer to the AN2653 on: www.st.com. 3.
PAGE 16
Application note 3.2 TS507 In-the-loop-compensation technique The second technique is called in-the-loop-compensation technique, because the additional components (a resistor and a capacitor) used to improve the stability are inserted in the feedback loop (see Figure 30). Figure 30. In-the-loop compensation schematics This compensation method allows (by a good choice of compensation components) the original pole caused by the capacitive load to be compensated. Stability is thus improved.
