LTC2057IS8#PBF

产品概述

The LTC2057IS8#PBF is a high voltage low noise zero-drift Operational Amplifier offers precision DC performance over a wide supply range 4.75 to 36V. 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 (typical). 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 (typical). In addition to low offset and noise, this amplifier features a 1.5MHz (typical) gain-bandwidth product and a 0.45V/µs (typical) slew rate. Wide supply range, combined with low noise, low offset and excellent PSRR and CMRR make LTC2057 well suited for high dynamic-range test, measurement and instrumentation systems.
