Two-channel CMOS op-amp with 28 MHz GBW
The AD8656ARZ-REEL from Analog Devices is a dual CMOS operational amplifier from the DigiTrim® series, offering a gain bandwidth product of 28 MHz and a slew rate of 11 V/µs. It operates from a single supply spanning 2.7 V to 5.5 V, draws 3.7 mA per channel, and delivers rail-to-rail output swing. The input bias current is 1 pA, making it suited for high-impedance sensor interfaces, photodiode amplifiers, and battery-powered instrumentation. The part is housed in an 8-SOIC package and rated for the industrial temperature range of -40°C to 125°C.
28 MHz GBW and 11 V/µs slew rate — signal chain fit
The 28 MHz gain bandwidth product and 11 V/µs slew rate suit fast ADC drivers and active filters.
Active production, no end-of-life concern
The AD8656ARZ-REEL carries an Active lifecycle status with ROHS3 compliance. No last-time-buy or obsolescence notice is in effect. The part is available through independent distribution and can be quoted to order against an RFQ.
Supply range and rail-to-rail output
The 2.7 V to 5.5 V supply span covers single-rail systems. Rail-to-rail output swing maximizes dynamic range.
