Product details

Single-supply precision op-amp for industrial signal chains

It delivers a gain-bandwidth product of 3.4 MHz and a slew rate of 1.2 V/µs, with a maximum input offset voltage of 75 µV and input bias current of 240 nA.

75 µV offset — where it earns its place on the BOM

In a weigh-scale or bridge amplifier, that offset translates directly to a DC error at the output.

Supplied in a Tube of 8-SOIC (0.154", 3.90 mm width) packages, surface-mount. The 8-SOIC footprint is standard for single op-amps; no special land pattern needed.

ADI lists the OP113ESZ as Active and ROHS3 compliant.

Frequently asked questions

What is the OP113ESZ equivalent?

Within the same performance tier, the ADA4077-1ARZ-R7 is a functional peer with a lower input offset voltage (15 µV vs 75 µV) and wider temperature range (-40°C to 125°C), but its output current is lower (22 mA vs 40 mA). The AD8675ARMZ offers rail-to-rail output and 10 MHz GBW, but at a higher supply current. Neither is a drop-in replacement — verify the pinout and compensation before substituting.

What is the difference between OP113ESZ and OP113ES?

The OP113ESZ suffix indicates ROHS3 compliance and a Tube package. The OP113ES (non-Z) may be non-ROHS or packaged differently. Check the specific order code for environmental compliance and packaging details.
