AD623AR-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD623AR-REEL7 is a single-supply, rail-to-rail instrumentation amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.3 V to 18 V and features a bandwidth of 1 MHz with a slew rate of 1 V/µs. Key electrical parameters include a maximum input offset voltage of 125 µV, a minimum common-mode rejection ratio of 73 dB, and an input bias current of 2 nA. The device draws a typical operating supply current of 400 µA and is housed in an 8-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as manufacturing processes may vary. Ensure the supplier provides valid traceability documentation for quality assurance. Check for any lead time constraints associated with this specific reel quantity. Validate that the component matches the original Analog Devices specification sheet.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-cost, single-supply instrumentation amplifier is required. It is suitable for applications needing rail-to-rail output capability. Consider its 1 MHz bandwidth for moderate-speed signal processing tasks. Evaluate its 400 µA supply current against battery life requirements. Compare its 73 dB CMRR against system noise immunity needs.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD623 family of instrumentation amplifiers designed for cost-sensitive applications. It serves as a drop-in replacement for discrete solutions, offering improved stability and linearity. The series is widely used in portable devices due to its low power consumption. It complements higher-performance models like the AD620 for general-purpose sensing.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD623ARMZ is a pin-compatible alternative in a different package. Verify thermal performance differences between SOIC and MSOP packages. Check if the Z suffix indicates updated RoHS compliance compared to non-Z versions. Ensure gain resistor values remain compatible across package variations.
