ADA4610-1ARZ

Overview

The ADA4610-1ARZ is a single-channel precision JFET operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output, low offset voltage (B grade: 0.4 mV max), and low input bias current (5 pA typical). Operating on dual supplies from ±5 V to ±15 V, it provides a gain bandwidth product of 16.3 MHz and a slew rate of 61 V/µs at ±15 V. The device operates within an extended temperature range of -40°C to +125°C and is housed in an 8-lead SOIC package.

Feature Summary

• Rail-to-rail output capability with no phase reversal when input voltages exceed the common-mode range
• Low noise performance with 7.3 nV/√Hz voltage noise density at 1 kHz
• High impedance JFET inputs providing very low input bias current
• Excellent DC precision with low offset voltage and drift

Applications

• Medical instruments
• Precision current measurement using shunts
• Photodiode amplifiers
• Multipole filters
• Audio applications

Procurement Notes

Verify the specific ordering suffix ARZ corresponds to the 8-lead SOIC package configuration. Confirm B-grade specifications for offset voltage if required for high-precision designs. Ensure supply voltage limits do not exceed ±18 V absolute maximum ratings during operation.

Selection Notes

Select this component for applications requiring high input impedance combined with low noise and precision. It is suitable for circuits driving capacitive loads due to fast settling times. Consider the 8-lead SOIC package constraints for thermal management and board space requirements.

Part Context

This part belongs to the ADA4610 family of low noise, precision, rail-to-rail output JFET op amps. The family includes single (ADA4610-1), dual (ADA4610-2), and quad (ADA4610-4) variants. The ADA4610-1ARZ specifically denotes the single-channel version in an 8-lead SOIC package.

Replacement Considerations

Direct substitutes include other parts from the ADA4610 family such as ADA4610-2 or ADA4610-4 if channel count differs. Other precision JFET op amps like AD8610 may be considered but require verification of pinout and electrical characteristics.
