Description

The LTC2050 and LTC2050HV are zero-drift operational amplifiers available in the 5- or 6-lead SOT-23 and SO-8 packages. The LTC2050 operates from a single 2.7V to 6V supply. The LTC2050HV operates on supplies from 2.7V to ±5.5V. The current consumption is 800µA and the versions in the 6-lead SOT-23 and SO-8 packages offer power shutdown (active low).

The LTC2050, despite its miniature size, features uncompromising DC performance. The typical input offset voltage and offset drift are 0.5µV 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 typically 1V from the positive supply. The LTC2050 also has an enhanced output stage capable of driving loads as low as 2k Ohm to both supply rails. The openloop gain is typically 140dB. The LTC2050 also features a 1.5µVP-P DC to 10Hz noise and a 3MHz gain bandwidth product.
