LTC2057/LTC2057HV High Voltage, Low Noise Zero-Drift Operational Amplifier Fea T Descrip T n Supply Voltage Range The LTC 2057 is a high voltage, low noise, zero-drift op- n 4.75V to 36V (LTC2057) erational amplifier that offers precision DC performance n 4.75V to 60V (LTC2057HV) over a wide supply range of 4.75V to 36V or 4.75V to n Offset Voltage: 4V (Maximum) 60V for the LTC2057HV. Offset voltage and 1/f noise are n Offset Voltage Drift: 0.015V/C suppressed, allowing this amplifier to achieve a maximum (Maximum, 40C to 125C) offset voltage of 4V and a DC to 10Hz input noise volt- n Input Noise Voltage age of 200nV (typ). The LTC2057s self-calibrating P-P n 200nV , DC to 10Hz (Typ) P-P circuitry results in low offset voltage drift with temperature, n 11nV/Hz, 1kHz (Typ) 0.015V/C (max), and zero-drift over time. The amplifier + n Input Common Mode Range: V 0.1V to V 1.5V also features an excellent power supply rejection ratio n Rail-to-Rail Output (PSRR) of 160dB and a common mode rejection ratio n Unity Gain Stable n (CMRR) of 150dB (typ). Gain Bandwidth Product: 1.5MHz (Typ) n Slew Rate: 0.45V/s (Typ) The LTC2057 provides rail-to-rail output swing and an n A : 150dB (Typ) VOL input common mode range that includes the V rail (V n PSRR: 160dB (Typ) + 0.1V to V 1.5V). In addition to low offset and noise, this n CMRR: 150dB (Typ) amplifier features a 1.5MHz (typ) gain-bandwidth product n Shutdown Mode and a 0.45V/s (typ) slew rate. a T Wide supply range, combined with low noise, low offset, n High Resolution Data Acquisition and excellent PSRR and CMRR make the LTC2057 and n Reference Buffering LTC2057HV well suited for high dynamic-range test, n Test and Measurement measurement, and instrumentation systems. n Electronic Scales L, LT, LTC, LTM, Linear Technology, Over-The-Top, and the Linear logo are registered n Thermocouple Amplifiers trademarks of Linear Technology Corporation.
