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 ±±  
V to ±1± 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 +12±°C. The AD8677 amplifier is  
available in the tiny, ±-lead TSOT and the popular 8-lead,  
narrow SOIC lead-free packages.
