The LTC2051/LTC2052 are dual/quad zero-drift operational amplifiers suitable for thermocouple amplifiers, electronic scales, medical instrumentation, strain gauge amplifiers, high-resolution data acquisition, etc. They feature a maximum offset voltage of 3μV, a maximum offset voltage drift of 30nV/°C, small footprint, low-profile MS8/GN16 packages, single supply operation from 2.7V to ±5.5V, noise of 1.5μVP-P (0.01Hz to 10Hz), voltage gain of 140dB, PSRR of 130dB, CMRR of 130dB, supply current of 0.75mA (per amplifier), and an operating temperature range of -40°C to 85°C.
The LTC2051/LTC2052 are dual‑ or quad‑channel zero‑drift operational amplifiers offered in MS8, MS10 and SO‑8/GN16 packages. They operate from a single 2.7 V supply up to +5.5 V and provide rail‑to‑rail output swings with low noise and high gain.
Key features include a maximum offset voltage of 3 µV, typical supply current of 0.75 mA per amplifier, a gain‑bandwidth product of 3 MHz, and operation over –40 °C to 85 °C. The datasheet provides absolute maximum ratings, electrical characteristics, package information, and typical application circuits.
