Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage of 4μV and a DC to 10Hz input noise voltage of 200n VP-P (typ). The LTC2057’s self-calibrating circuitry results in low offset voltage drift with temperature, 0.015μV/°C (max), and zero-drift over time. The amplifier also Features an excellent power supply rejection ratio (PSRR) of 160d B and a mon mode rejection ratio (CMRR) of 150d B (typ). The LTC2057 provides rail-to-rail output swing and an input mon mode range that includes the V- rail (V- - 0.1V to V+ - 1.5V). In addition to low offset and noise, this amplifier Features a 1.5MHz (typ) gain-bandwidth product and a 0.45V/μs (typ) slew rate. Wide supply range, bined with low noise, low offset, and excellent PSRR and CMRR make the LTC2057 and LTC2057HV well suited for high dynamic-range test, measurement, and instrumentation systems.
