7.3 Feature Description

The TLC227x and TLC227xA family of devices feature 2-MHz bandwidth and voltage noise of 9 nV/√Hz with performance rated from 4.4 V to 16 V across an automotive temperature range (–40°C to 125°C). LinMOS suits a wide range of audio, automotive, industrial, and instrumentation applications.

7.4 Device Functional Modes

The TLC227x and TLC227xA families of devices is powered on when the supply is connected. The devices may operate with single or dual supply, depending on the application. The devices are in its full performance once the supply is above the recommended value.
