Product Details
The LTC2057 is a high voltage, low noise, zero-drift operational amplifier that offers precision DC performance over a wide supply range of 4.75V to 36V or 4.75V to 60V for the LTC2057HV. 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 200nVP-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 160dB and a common mode rejection ratio (CMRR) of 150dB (typ).
The LTC2057 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, this amplifier features a 1.5MHz (typ) gain-bandwidth product and a 0.45V/μs (typ) slew rate.
Wide supply range, combined 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.
