AD8602ARZ

Overview

The AD8602ARZ is a dual 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 slew rate of 6 V/µs at 5 V, and a maximum offset voltage of 500 µV for the A grade. Input bias current is typically 60 pA. It is housed in an 8-lead SOIC package and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output architecture maximizes dynamic range in low-voltage single-supply systems.
• DigiTrim technology provides superior DC precision without laser trimming.
• CMOS input stage ensures extremely low input bias currents suitable for high impedance sources.
• Unity-gain stable design eliminates phase reversal during overdrive conditions.

Applications

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

Procurement Notes

Verify the specific grade suffix (e.g., ARZ) against the required offset voltage specifications, as D grades offer lower DC precision. Confirm that the 8-lead SOIC package matches the target PCB footprint. Ensure the selected variant meets the necessary automotive qualification standards if applicable to the end-use environment.

Selection Notes

Select this component when both wide signal bandwidth and high DC accuracy are required in a single-supply environment. The dual configuration allows designers to implement complex filter stages or differential circuits within a compact footprint. Consider the trade-off between the A grade's tighter offset limits and potential cost implications compared to the D grade.

Part Context

This part belongs to the AD860x family, which includes single (AD8601), dual (AD8602), and quad (AD8604) variants. All members share identical electrical characteristics and utilize the same patented DigiTrim process. The family is designed to provide consistent performance across different channel counts while maintaining compatibility with standard op amp pinouts.

Replacement Considerations

Direct functional replacements include other parts within the AD860x series such as the AD8601 or AD8604, provided the channel count difference is acceptable. Verify that any substitute maintains the rail-to-rail I/O specification and the 2.7 V minimum supply requirement.
