7.3 Feature Description
The TLC227x-Q1 family features 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-Q1 family of devices is powered on when the supply is connected. The device can operate with
single or dual supply, depending on the application. The device is in its full performance once the supply is above
the recommended value.
