AD8677AUJZ-R2 GENERAL DESCRIPTION

The AD8677 is the next generation of precision, ultralow offsetamplifiers. It builds on the high performance of the OP07 andintegrates lower power (1.1 mA typical), lower input biascurrent (±1 nA maximum), and higher CMRR/PSRR (130 dB)in the small TSOT package. Operation is fully specified from ±5V to ±15 V supply.The AD8677 provides higher accuracy than industry-standardOP07-type amplifiers due to Analog Devices’ iPolar™ process,which supports enhanced performance in a smaller footprint.These performance enhancements include wider output swing,lower power, and higher CMRR (common-mode rejectionratio) and PSRR (power supply rejection ratio). The AD8677maintains stability of offsets and gain virtually regardless ofvariations in time or temperature. Excellent linearity and gainaccuracy can be maintained at high closed-loop gains.The AD8677 is fully specified over the extended industrial tem-perature range of −40°C to +125°C. The AD8677 amplifier isavailable in the tiny, 5-lead TSOT and the popular 8-lead,narrow SOIC lead-free packages.
