The LTC
2051/LTC2052 are dual/quad zero-drift opera-
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/
LTC2052 also feature a 1.5μVP-P DC to 10Hz noise and a
3MHz gain-bandwidth product.
Input Referred Noise 0.1Hz to 10Hz
