AD8604DRZ

Overview

The AD8604DRZ is a quad precision CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical supply current of 750 µA per amplifier. The device offers an 8.4 MHz gain bandwidth product, a 6 V/µs slew rate at 5 V, and a maximum offset voltage of 6000 µV for the D grade. It utilizes DigiTrim technology for post-assembly trimming and is housed in a 14-lead SOIC package.

Feature Summary

• Rail-to-rail input and output architecture maximizes dynamic range in low-voltage single-supply systems.
• DigiTrim technology provides superior DC precision through post-package offset voltage trimming without laser modification.
• CMOS input stage ensures extremely low input bias currents suitable for high source impedance applications.

Applications

• Current sensing circuits
• Barcode scanners
• Battery-powered instrumentation
• Multipole filters

Procurement Notes

Verify that the specific part number matches the required package type and temperature range. Confirm the grade (e.g., D Grade) aligns with the necessary DC precision specifications. Ensure compatibility with the intended single-supply voltage levels and load conditions before finalizing procurement.

Selection Notes

Select this component when a quad configuration is required alongside rail-to-rail performance and low power consumption. Consider the D grade specifications if higher offset voltages are acceptable for cost reduction. Verify thermal resistance requirements for the surface-mount application environment.

Part Context

This component belongs to the AD8601/AD8602/AD8604 family of wideband operational amplifiers manufactured by Analog Devices Inc. The family includes single, dual, and quad variants sharing identical electrical characteristics and pinout compatibility across different package options.

Replacement Considerations

Direct replacements include other members of the AD860x family such as the AD8602 or AD8601, provided the channel count meets the design requirements. Cross-referencing with similar rail-to-rail CMOS amplifiers requires verifying gain bandwidth and offset voltage limits.
