The LTC2054 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 5.5V. The current consumption is 150A (typical), 175A maximum over temperature. The LTC2054, despite its miniature size, features uncompromising DC performance. The typical input offset voltage and offset drift are 0.5V and 25nV/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.
