LTC2051/LTC2052
Dual/Quad Zero-Drift
Operational Amplifiers
U
DESCRIPTIO
The LTC®2051/LTC2052 are dual/quad zero-drift operational 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 consumption is 750μA per op amp.
The LTC2051/LTC2052, despite their miniature size, feature 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
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 1.5μV
3MHz gain-bandwidth product.
