The LTC

tional amplifiers available in the MS8 and SO-8/GN16 and

S14 packages. For space limited applications, the LTC2051

is available in a 3mm × 3mm × 0.8mm dual fine pitch

leadless package (DFN). They operate from a single 2.7V

supply and support ±5V applications. The current con-

sumption is 750μA per op amp.

The LTC2051/LTC2052, despite their miniature size, fea-

ture 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 rejec-

tion 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

LTC2051/LTC2052 also have an enhanced output stage

capable of driving loads as low as 2kΩ to both supply rails.

The open-loop gain is typically 140dB. The LTC2051/

3MHz gain-bandwidth product.

Input Referred Noise 0.1Hz to 10Hz
