Supply span runs from 5 V minimum to 30 V maximum, so it works on a single 5 V rail or a ±15 V split supply without a secondary regulator. Input bias current of 70 nA matters when your source impedance climbs above 10 kΩ: that 70 nA across a 10 kΩ source adds 700 µV of offset error, which lands right on top of the 250 µV intrinsic offset. Keep source impedance balanced and below 1 kΩ for best DC accuracy. The output type is differential, which means the two outputs swing in opposite polarity around a common-mode voltage. This pairs directly with a differential-input ADC — you get twice the signal swing for a given supply and cancel common-mode noise picked up on the board. If your ADC has a single-ended input, you'll need a differential-to-single-ended converter stage or an instrumentation amp with a single-ended output. Check your ADC front-end before committing the board layout.","metaTitle":"OP221GSZ Dual Instrumentation Amplifier, 600kHz","metaDescription":"ADI OP221GSZ dual instrumentation amp in 8-SOIC. 600 kHz bandwidth, 0.3 V/µs slew rate, 850 µA per channel, -55°C to 125°C range.
