LTC2057IS8#PBF

LTC2057 is a high voltage, low noise, zero-drift operational amplifier. Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage and a DC to 10Hz input noise voltage of 200nVP-P (typ). It is self-calibrating circuitry results in low offset voltage drift with temperature and zero-drift over time. This provides rail-to-rail output swing and an input common mode range that includes the V– rail (V– –0.1V to V+ – 1.5V). In addition to low offset and noise. Wide supply range, combined with low noise, low offset, and excellent PSRR and CMRR make this product well suited for high dynamic-range test, measurement, and instrumentation systems. Typical applications are high resolution data acquisition, reference buffering, test and measurement, electronic scales, thermocouple amplifiers, strain gauges, low-side current sense, automotive monitors and control.
