What this dual CMOS op-amp brings to the board
The AD8656ARMZ-REEL from Analog Devices is a dual-channel CMOS operational amplifier from the DigiTrim® family, packing 28 MHz gain-bandwidth and an 11 V/µs slew rate into an 8-MSOP footprint. 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. The -40°C to 125°C range clears automotive under-hood and industrial outdoor enclosures without a second temperature-grade variant.
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
Each channel can source or sink 220 mA, which is unusually high for a precision CMOS op-amp. 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.
Lifecycle and sourcing — active, no obsolescence concern
ADI lists the AD8656ARMZ-REEL as Active product status. The part is sourced through independent distribution and quoted to order against an RFQ; availability and current pricing are confirmed at quote time.
