Product details

The rail-to-rail output stage lets it swing close to the supply rails in single-supply circuits from 5 V logic rails up to 36 V industrial buses. Supply current is 700 µA per amplifier — moderate for a JFET part, but the low bias current and wide supply range often justify the power budget in instrumentation and data-acquisition front ends.

Package and footprint — 8-MSOP, surface-mount only

The 8-MSOP is a common footprint for precision op-amps, and the pinout is standard for single JFET amplifiers: offset null, inverting input, non-inverting input, negative supply, output, positive supply, and two null terminals. The 20 mA output current per channel is adequate for driving ADC inputs or moderate loads, but not for heavy analog outputs without a buffer.

Temperature range and deployment environments

It is not qualified to AEC-Q100, so it is not recommended for under-hood automotive or extended -40°C to 125°C environments. The 400 µV maximum input offset voltage is typical for a JFET op-amp at this price point; if sub-100 µV offset is required, consider a precision bipolar or auto-zero amplifier instead.

Frequently asked questions

What is the AD820ARMZ-R7 equivalent?

The closest functional equivalent within the same ADI family is the AD820ARZ-REEL, which shares the same 1.8 MHz gain bandwidth, 3V/µs slew rate, 2 pA input bias, and rail-to-rail output, but comes in an SOIC-8 package instead of MSOP. If you need a wider bandwidth, the AD8627AKSZ-REEL7 offers 5 MHz and 5V/µs in a SC-70-5 package, though it is a single amplifier with lower output current (15 mA). For a quad-channel alternative, the AD8625ARZ-REEL7 packs four amplifiers with the same 5 MHz bandwidth in an SOIC-14 package.

Can AD820ARMZ-R7 be used in single-supply circuits?

Yes. The rail-to-rail output stage allows the output to swing within millivolts of both supply rails, and the input common-mode range extends from the negative rail to within about 1.1 V of the positive rail. For a 5 V single supply, the input range is approximately 0 V to 3.9 V, which covers most sensor and ADC interface signals. The supply voltage range of 5 V to 36 V means it works on a single 5 V logic rail or a 24 V industrial bus without a split supply.

Is AD820ARMZ-R7 a single or dual op amp?

It is a single op-amp (one circuit) in an 8-pin MSOP package. For dual or quad channel counts, look at the AD822 (dual) or AD824 (quad) families from the same JFET series.
