NCS7101
1.8 Volt Rail−to−Rail
Operational Amplifier
The NCS7101 operational amplifier provides rail−to−rail operation
on both the input and output. The output can swing within 50 mV of
each rail. This rail−to−rail operation enables the user to make full use
of the entire supply voltage range available. It is designed to work at
very low supply voltages (1.8 V and ground), yet can operate with a
supply of up to 10 V and ground. The NCS7101 is available in the
space saving SOT−23−5 package with two industry standard pinouts.
