What this dual CMOS op-amp brings to the board
It swings rail-to-rail on the output, runs on a 2.7 V to 5.5 V supply span, and draws 3.7 mA per channel. The 1 pA input bias current and 50 µV input offset voltage suit precision sensor conditioning — photodiode transimpedance, thermocouple buffers, or battery-monitor front-ends.
28 MHz GBW and 11 V/µs slew — where the bandwidth lands
A 28 MHz gain-bandwidth product and 11 V/µs slew rate suit audio processing, motor-current shunt amplifiers, or mid-speed ADC drivers.
220 mA output current — drives loads without a buffer
That lets it drive low-impedance loads directly — headphones, long twisted-pair cables, or the analog input of multiple SAR ADCs — without adding an external line driver.
ADI lists the AD8656ARMZ-REEL as Active product status.
