AD8675ARZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8675ARZ-REEL7 is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output swing, ultralow offset voltage (max 75 µV), and low input bias current (max 2 nA). The device operates on supply voltages from ±5 V to ±18 V with a typical gain bandwidth product of 10 MHz and a slew rate of 2.5 V/µs. It provides high open-loop gain (120 dB) and low voltage noise density (2.8 nV/√Hz). The component is housed in an 8-lead narrow SOIC package and supports an extended industrial operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features proprietary nulling capability via dedicated pins to externally compensate for combined device and system offset errors up to 3.5 mV without degrading CMRR or PSRR.
• Delivers rail-to-rail output swing while maintaining very low input bias current and low input current noise compared to other low-noise rail-to-rail amplifiers.
• Combines wide bandwidth and low voltage noise with the precision and low power consumption characteristics typically found in industry-standard precision amplifiers.

Instrumentation, Op Amps, Buffer Amps Applications

• Precision instrumentation
• PLL filters
• Strain gage amplifiers
• Medical instrumentation
• Thermocouple amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the received component matches the AD8675ARZ-REEL7 designation and corresponds to the 8-lead Standard Small Outline Package (R-8). Confirm RoHS compliance status as indicated by the Z suffix. Ensure the supplier documentation aligns with the manufacturer's ordering guide specifications for this specific reel variant.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when applications require both rail-to-rail output capability and ultra-low DC error sources such as offset voltage and drift. It is suitable for designs needing low input bias current alongside wide bandwidth. Consider the external nulling feature if system-level offset compensation is required without affecting AC performance parameters like common-mode rejection.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8675 belongs to a series of low-noise operational amplifiers offered by Analog Devices. It serves as the single-channel counterpart to the dual-channel AD8676. The device shares design similarities with the OP184 regarding output swing but offers superior bandwidth and lower noise, while matching the precision and low power profile of the OP07.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

For equivalent functionality, consider the AD8675ARMZ-REEL or standard AD8675ARZ variants which share identical electrical specifications. The AD8676 serves as the dual-channel alternative within the same family.
