DESCRIPTIO
Maximum Offset Voltage of 3V Maximum Offset Voltage Drift of 30nV/C Small Footprint, Low Profile MS8 Package Noise: 1.5VP-P (0.1Hz to 10Hz Typ) Voltage Gain: 140dB (Typ) PSRR: 130dB (Typ) CMRR: 130dB (Typ) Supply Current: 0.75mA (Typ) per Amplifier Single Supply Operation: 2.7V to 11V Extended Common Mode Input Range Output Swings Rail-to-Rail Overload Recovery Time: 2ms (Typ) Operating Temperature Range -40C to 85C
The LTC(R)2051 is a dual zero-drift operational amplifier available in the MS8 and SO-8 packages. It operates from a single 2.7V supply while still supporting 5V applications. The power consumption is 750A per op amp. The LTC2051, despite its miniature size, features uncompromising DC performance. The typical input offset voltage and offset drift are 0.5V and 10nV/C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB. The input common mode voltage ranges from the negative supply up to 1V from the positive supply. The LTC2051 also has an enhanced output stage capable of driving loads as low as 1k to both supply rails. The open-loop gain, loaded with 1k, is in excess of 140dB. The LTC2051 also features a 1.5VP-P DC to 10Hz noise and a 3MHz gain bandwidth product.

Note 1: Absolute Maximum Ratings are those values beyond which the life of the device may be impaired. Note 2: These parameters are guaranteed by design. Thermocouple effects preclude measurements of these voltage levels during automated testing.
Note 3: The LTC2051C, LTC2051HVC is guaranteed to meet specified performance from 0C to 70C and is designed, characterized and expected to meet these extended temperature limits, but is not tested at - 40C and 85C. The LTC2051I, LTC2051HVI is guaranteed to meet the extended temperature limits.
