DESCRIPTIO
November 1999
The LTC®2050 is a low drift operational amplifier available
in the 5- or 6-lead SOT-23 and SO-8 packages. It operates
from a single 2.7V supply while still supporting 5V appli-
cations. The power consumption is 800µA and the ver-
sions 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 0.5µV 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 negative
supply up to 1V from the positive supply. The LTC2050
also has an enhanced output stage capable of driving
loads as low as 1kΩ to both supply rails. The open-loop
gain, loaded with 1kΩ, is in excess of 140dB. The LTC2050
also features a 1.5µVP-P DC to 10Hz noise and a 3MHz gain
bandwidth product.
