DESCRIPTION

The LTC

ampliﬁ ers 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 LTC2050, despite its miniature size, features uncom-

promising 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 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

bandwidth product.
