Who has never experienced oscillations issues when using an operational amplifier? Opampsare often used in a simple voltage follower configuration. However, this is not the bestconfiguration in terms of capacitive loading and potential risk of oscillations.Capacitive loads have a big impact on the stability of operational amplifier-basedapplications. Several compensation methods exist to stabilize a standard op-amp. Thisapplication note describes the most common ones, which can be used in most cases.The general theory of each compensation method is explained, and based on this, specific
data is provided for the TS507. The TS507 is a high precision rail-to-rail amplifier, with verylow input offset voltage, and a 1.9 MHz gain bandwidth product, which is available in
SOT23-5 and SO-8 packages.
This document simplifies the task of designing an application that includes the TS507. Itspares you the time-consuming effort of trying numerous combinations on bench, and it isalso much more accurate than using Spice models which are not designed to study systemstability, even though they can give a general trend.
