LTC2050

The LTC® 2050 is a low drift operational amplifier available in the 5- or 6-lead SOT-23 and SO-8 packages. It operates from a single 2.7V supply while still supporting 5V appli-cations. The power consumption is 800µA and the ver-sions in the 6-lead SOT-23 and SO-8 packages offer power shutdown (active low).

The LTC2050, despite its miniature size, features uncom- promising DC performance. The typical input offset volt-age 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 1V from the positive supply. The LTC2050 also has an enhanced output stage capable of driving loads as low as 1kΩ to both supply rails. The open-loop gain, loaded with 1kΩ, is in excess of 140dB. The LTC2050 also features a 1.5µVP-P DC to 10Hz noise and a 3MHz gain bandwidth product.
