The LTC2057HVIMS#PBF is a high precision zero-drift operational amplifier from Linear Technology. It utilizes a proprietary auto-zeroing technique to achieve an input offset voltage of just 0.5 μV typical at 25°C, with an average drift of only 0.015 μV/°C over the full –40°C to 125°C temperature range. The amplifier offers a gain bandwidth product of 1.5 MHz and a slew rate of 1.3 V/μs rising and 0.45 V/μs falling.
With a typical open-loop gain of 150 dB and common mode rejection ratio of 150 dB, the LTC2057HV is suitable for high-side current sensing and precision signal conditioning. The supply voltage range is 4.75V to 36V, and the quiescent current is only 1.35 mA. A shutdown feature reduces supply current to 3 μA, making it ideal for battery-powered applications.
The amplifier is designed for use in precision instrumentation, medical equipment, and industrial control systems where low offset and drift over temperature are critical.
