The LTC
廬
2054 and LTC2054HV are low power, low noise
zero-drift operational amplifiers available in the
5-lead SOT-23 package. The LTC2054 operates from a
single 2.7V to 6V supply. The LTC2054HV operates on
supplies from 2.7V to
鹵5.5V.
The current consumption is
150碌A(chǔ) (typical), 175碌A(chǔ) maximum over temperature.
The LTC2054, despite its miniature size, features uncom-
promising DC performance. The typical input offset volt-
age and offset drift are 0.5碌V and 25nV/擄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 typically 0.5V from the positive supply. The
open-loop gain is typically 140dB. The LTC2054 also
features a 1.6碌V
P-P
DC to 10Hz noise and a 500kHz gain
bandwidth product.
