1 Designing for TLV90xxS operational amplifiers with shutdown

This document discusses the shutdown variants of the TLV90xx device family. Amplifiers with the shutdown feature allow the designer to choose when the amplifier is enabled, thereby offering power saving benefits. This is especially useful in battery powered applications. Topics covered include shutdown parameters, transient behaviors, enable time and shutdown time factors, device performance while in shutdown and signal muxing with shutdown devices.
