DESCRIPTION
Zero-Drift Operational Amplifiers in SOT-23
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 800µA and
the versions in the 6-lead SOT-23 and SO-8 packages
offer power shutdown (active low). The LTC2050HVMP
offer operating range from 4.5V to ±5.5V and operating
temperature range of – 55°C to 150°C.
The LTC2050, despite its miniature size, features uncom-
promising DC performance. The typical input offset volt-
age and offset drift are 0.5µV and 10nV/°C. The almost
zero DC offset and drift are supported with a power sup
-
ply rejection ratio (PSRR) and common mode rejection
ratio(CMRR) of more than 130dB.
The input common mode voltage ranges from the nega
-
tive supply up to typically 1V from the positive supply.
The LTC2050 also has an enhanced output stage capable
of driving loads as low as 2kΩ to both supply rails. The
open-loop gain is typically 140dB. The LTC2050 also
features a 1.5µV
P-P
DC to 10Hz noise and a 3MHz gain
bandwidth product.
