The LTC
2050 and LTC2050HV are zero-drift operational
amplifiers available in the 5- or 6-lead SOT-23 and SO-8
packages. The LTC2050 operates from a single 2.7V to 6V
supply. The LTC2050HV operates on supplies from 2.7V
to
±5.5V. The current consumption is 800A and the
versions 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 0.5
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 typically 1V from the positive supply. The
LTC2050 also has an enhanced output stage capable of
driving loads as low as 2k
to both supply rails. The open-
loop gain is typically 140dB. The LTC2050 also features a
1.5
VP-P DC to 10Hz noise and a 3MHz gain bandwidth
product.
