ESCRIPTIO
The LTC
2051 is a dual zero-drift operational amplifier
available in the MS8 and SO-8 packages. It operates from
a single 2.7V supply while still supporting
±
5V applica-
tions. The power consumption is 750
μ
A per op amp.
The LTC2051, despite its miniature size, features uncom-
promising DC performance. The typical input offset volt-
age and offset drift are 0.5
μ
V 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 LTC2051
also has an enhanced output stage capable of driving
loads as low as 1k
to both supply rails. The open-loop
gain, loaded with 1k
, is in excess of 140dB. The LTC2051
also features a 1.5
μ
V
P-P
DC to 10Hz noise and a 3MHz gain
bandwidth product.
