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.
