Product details

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.

Frequently asked questions

Can AD8656ARMZ-REEL be used in single supply applications?

Yes — the rail-to-rail output and 2.7 V to 5.5 V supply span allow single-supply operation from 3.3 V or 5 V rails. The input common-mode range includes ground, so it works as a single-supply buffer or non-inverting amplifier.

What is the difference between AD8656ARMZ-REEL and AD8656ARZ?

The AD8656ARMZ-REEL and AD8656ARZ are electrically identical — same 28 MHz GBW, 11 V/µs slew, 1 pA bias, and 220 mA output. The difference is packaging: ARMZ is the 8-MSOP variant, while ARZ is the 8-SOIC. The MSOP saves about 30% board area but has higher thermal resistance, so continuous high-current drive at elevated temperature is more constrained in the MSOP.
