LT LTC2057HVHS8#PBF

Zero-DriftRail-to-Rail1,5 МГц

Overview

The LTC®2057 is a high-voltage, low-noise, zero-drift operational amplifier that offers precision DC performance over a wide-supply range of 4.75 V to 36 V, or 4.75 V to 60 V for the LTC2057HV. Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage of 4 μV and a DC to 10 Hz input noise voltage of 200 nVP-P (typ). The LTC2057’s self-calibrating circuitry results in low-offset voltage drift with temperature, 0.015 μV/°C (max), and zero-drift over time. The amplifier also features an excellent power supply rejection ratio (PSRR) of 160 dB and a common-mode rejection ratio (CMRR) of 150 dB (typ). The LTC2057 provides rail-to-rail output swing and an input common-mode range that includes the V– rail (V– – 0.1 V to V+ – 1.5 V). In addition to low-offset and noise, this amplifier features a 1.5 MHz (typ) gain-bandwidth product and a 0.45 V/μs (typ) slew rate. Wide-supply-range, combined with low-noise, low-offset, and excellent PSRR and CMRR make the LTC2057 and LTC2057HVHS8PBF well suited for high-dynamic-range test, measurement, and instrumentation systems.
