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 temperature 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.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
