AMP771
Low Offset RRO Operational Amplifier
General Description
The AMP771 is Single low noise precision operational
amplifiers intended for use in a wide range of applications.
The AMP771 can operation in temperature range of –40°C to
125°C with low input bias current. AMP771 is characterized to
operate supply voltage range 2.7V to 5V with operating
temperature range of −40°C to 85°C.
The AMP771is designed for precision, low noise, low voltage,
and miniature systems. It provides rail-to-rail output swing
into heavy loads. The maximum input offset voltage for the
AMP771 is TBD µV at room temperature and the input
common mode voltage range includes ground.
