AD8604DRU

Overview

The AD8604DRU 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 MHz gain bandwidth product, a slew rate of 5 V/µs, and a maximum offset voltage of 6000 µV for the D grade. Input bias current is typically 0.2 pA, ensuring minimal loading on high-impedance sources.

Feature Summary

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

Applications

• Current sensing
• Barcode scanners
• PA controls
• Battery-powered instrumentation
• Multipole filters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Confirm that the D grade meets the required DC precision limits for your application, as it offers lower accuracy compared to A grade variants. Ensure compatibility with the intended operating temperature range and supply voltage constraints before finalizing procurement.

Selection Notes

Select this component when cost-sensitive designs require wide signal bandwidth and rail-to-rail performance. The D grade is appropriate where moderate DC precision suffices. Consider the 14-lead TSSOP or SOIC packages for surface-mount integration. Evaluate the trade-off between the lower offset voltage of higher grades versus the cost benefits of the D grade.

Part Context

This part belongs to the AD860x family of precision amplifiers, which includes single (AD8601), dual (AD8602), and quad (AD8604) configurations. The family utilizes Analog Devices' patented DigiTrim technology to achieve low offset voltages and drift. These amplifiers are designed for general-purpose precision applications requiring wide bandwidth and low power consumption.

Replacement Considerations

Check for automotive qualified versions such as the AD8604WARZ if AEC-Q100 compliance is required. Verify pinout compatibility with existing designs when substituting with other quad op-amps from different manufacturers.
