LTC2057/LTC2057HV

High Voltage, Low Noise

Zero-Drift Operational Amplifier

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 200nV

P-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.
