LTC2050/LTC2050HV

Zero-Drift Operational Amplifiers in SOT-23

FEATURES

DESCRIPTION

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.
