Wide voltage gain selectable amplifier offers one-chip solution
The Analog Devices LT1997 Wide Voltage Gain Selectable Amplifier is a one-chip solution for accurately amplifying voltages.
The device consolidates a precision operational amplifier with highly-matched resistors. Gains from –13 to +14 with an accuracy of 0.006% (60ppm) can be accomplished using no external components. The device is perfect for use as a difference amplifier, where the superior resistor matching results in a common mode rejection ratio of greater than 91dB.
Typical applications include high side or low side current sensing; bidirectional wide common mode range current sensing; high voltage to low voltage level translation; industrial data-acquisition front-ends; replacement for isolation circuits; and differential to single-ended conversion.
