Overview
The AD8677ARZ from Analog Devices Inc. is a next-generation precision, ultralow offset operational amplifier. It builds on the high performance of the OP07 and integrates lower power consumption, lower input bias current, and higher common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) in a compact package. The AD8677 utilizes Analog Devices' iPolar™ process, which enhances performance in a smaller footprint, offering wider output swing, lower power, and higher CMRR and PSRR. This amplifier is fully specified over the extended industrial temperature range of −40°C to +125°C and is available in 5-lead TSOT and 8-lead SOIC lead-free packages.
