AD8604DRUZ

Overview

The AD8604DRUZ 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 utilizes DigiTrim technology for offset voltage correction without laser trimming, achieving a maximum offset voltage of 6000 µV in the D grade. Key dynamic specifications include an 8 MHz gain bandwidth product and a slew rate of 5 V/µs. It is designed for extended industrial temperature operation from -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output stages maximize usable voltage range in single-supply systems.
• DigiTrim technology provides post-assembly offset voltage correction without laser trimming.
• Low input bias current enables use in high source impedance applications.
• Unity-gain stable design ensures stability across various feedback configurations.

Applications

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

Procurement Notes

Verify the specific D grade performance parameters against system requirements, as they differ from A grade specifications. Confirm the 14-lead TSSOP package dimensions match the PCB footprint. Ensure the operating temperature range covers the intended environmental conditions. Check for automotive qualification if required by the application standard.

Selection Notes

Select this component when cost-sensitive precision is needed alongside wide signal bandwidth. The D grade offers lower DC precision compared to A grade but maintains AC performance suitable for audio and general-purpose amplification. Consider the low supply current for battery-operated designs. Verify that the rail-to-rail output swing meets the load requirements at the specific supply voltage.

Part Context

This part belongs to the AD860x family of precision CMOS operational amplifiers, which includes single (AD8601), dual (AD8602), and quad (AD8604) variants. The family shares common architectural features such as DigiTrim technology and rail-to-rail I/O. The AD8604 specifically integrates four independent amplifiers in a compact surface-mount package, facilitating multi-channel signal processing in space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements within the same family include AD8604ARU and AD8604ARUZ. For higher precision requirements, consider the A grade variant AD8604ARUZ. Cross-family replacements may require schematic review due to differences in offset voltage and bandwidth specifications.
