Description
The LTC®2057 is a high voltage, low noise, zero-drift op-
erational 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 volt-
age 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 Vrail (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 andhttp://www.DataSheet4U.net/
LTC2057HV well suited for high dynamic-range test,
measurement, and instrumentation systems.
