LT1997 Wide Voltage Gain Selectable Amplifier

Analog Devices Inc. LT1997 Wide Voltage Gain Selectable Amplifier is a one-chip solution for accurately amplifying voltages. The LT1997 combines a precision operational amplifier with highly-matched resistors. The LT1997 is ideal for use as a difference amplifier, where the excellent resistor matching results in a common mode rejection ratio of greater than 91dB.
