AD8643ACPZ-REEL7

Overview

The AD8643ACPZ-REEL7 is a quad, low-power, precision JFET input operational amplifier featuring rail-to-rail output capability. It operates on single supplies from 5 V to 26 V or dual supplies of ±2.5 V to ±13 V. Key electrical characteristics include a maximum supply current of 250 μA per amplifier, an input bias current of 1 pA maximum, and an offset voltage of 750 μV maximum. The device offers a gain bandwidth product of 3.5 MHz and a slew rate of 2 V/μs at ±13 V. It is housed in a 16-lead LFCSP package.

Feature Summary

Extremely low input bias current suitable for high-impedance signal sources
Rail-to-rail output swing capability for maximizing dynamic range
Low power consumption with unity-gain stability

Applications

Photodiode amplifiers
Precision current sensing
Medical instrumentation
Portable audio equipment

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the LFCSP-16 package dimensions match your PCB footprint design. Ensure the RoHS compliant status aligns with your manufacturing environmental regulations.

Selection Notes

Select this component when multiple channels are required in a compact form factor. The quad configuration reduces board space compared to individual single-channel amplifiers. Consider the LFCSP exposed pad connection requirements for thermal management and proper circuit operation during layout.

Part Context

This part belongs to the AD864x family of low power, rail-to-rail output, precision JFET amplifiers manufactured by Analog Devices Inc. The AD8643 specifically provides four independent amplifier channels within a single integrated circuit package, designed for applications requiring multiple precision signal conditioning stages.
