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.
