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.
The AD8677 provides higher accuracy than industry-standard
OP07-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 rejection
ratio) and PSRR (power supply rejection ratio). The AD8677
maintains stability of offsets and gain virtually regardless of
variations in time or temperature. Excellent linearity and gain
accuracy 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 is
available in the tiny, 5-lead TSOT and the popular 8-lead,
narrow SOIC lead-free packages.
