AD620ARZ-REEL7

AD620ARZ-REEL7 is the 7-inch-reel SOIC-8 ordering code for the Analog Devices AD620 instrumentation amplifier, written word-for-word in the ordering guide of the maker’s datasheet, where the Z marks the RoHS-compliant form; Analog Devices’ own EngineerZone listing states the AD620 status as Production. Every figure here is read on the A-grade rows of the maker’s current datasheet (Rev. H, Table 2; typicals at 25 °C on ±15 V unless a row states otherwise): input offset voltage of 125 µV maximum at 25 °C and 185 µV maximum over temperature, input offset current of 1 nA maximum at 25 °C and 1.5 nA maximum over temperature, input bias current of 2 nA maximum at 25 °C, and offset drift of 1 µV/°C maximum. The family-common figures are supplies from ±2.3 V to ±18 V, quiescent current of 1.3 mA maximum at 25 °C (1.6 mA maximum over temperature), and gain set from 1 to 10,000 by a single external resistor. An earlier version of this page named the 2 nA bias-current maximum as the offset current and carried the 25 °C offset-voltage and quiescent-current maxima without their temperature scope; both are corrected here. The tighter offset figures quoted for this family belong to the B grade and do not apply to this A-grade code. The selection point is a complete three-op-amp instrumentation amplifier in one package for bridge sensors, weigh scales and precision front ends, where a discrete build would drift apart. Selection advice: at high gain the A-grade offset and drift dominate the error budget, so price the B grade honestly against a system-level calibration step before defaulting to the cheaper code. Parameters verified against the Analog Devices AD620 datasheet Rev. H (ordering guide and Table 2, A-grade rows).
