GENERAL DESCRIPTION

The AD8677 is the next generation of precision, ultralow offset amplifiers. It builds on the high performance of the OP07 and integrates lower power (1.1 mA typical), lower input bias current (±1 nA maximum), and higher CMRR/PSRR (130 dB) in the small TSOT package. Operation is fully specified from ±5 V to ±15 V supply.

FEATURES

Low offset voltage: 130 μV max

Input offset drift: 1.5 μV/°C max

Low noise: 0.25 μV p-p

High gain, CMRR and PSRR: 115 dB min

Low supply current: 1.1 mA

Wide supply voltage range: ±4 V to ±18 V operation
