Product Overview
LT®1997-2 is an attenuating (funnel) difference amplifier that can be used to translate large differential signals to the low voltage range compatible with ADCs. It combines a precision operational amplifier with highly-matched resistors to form a one-chip solution to attenuate and level shift voltages accurately using no external components. Typical applications include high voltage to low voltage level translation, ADC driver, bidirectional wide common mode range voltage and current sensing, industrial data-acquisition front-ends, replacement for isolation circuits and differential to single-ended conversion.
- Wide supply voltage range: 3.3V to 50V
- ±255V common mode voltage range, 105dB minimum CMRR (Gain = 0.1)
- 350µA typ supply current, ±80µV maximum op-amp offset voltage
- 0.006% (60ppm) maximum gain error and ±1ppm/°C maximum gain error drift
- ±2ppm maximum gain nonlinearity, 1MHz -3dB bandwidth (gain = 0.1)
- 0.75V/µs slew rate, 16µs turn-on time
- Rail-to-rail output and low power shutdown: 20µA
- Precision attenuation: gain = 0.1, 0.2, 0.25
- 14 lead DFN-EP package
- Operating temperature range from -40 to 125°C
