ADA4610-2ARZ-RL

Overview

The ADA4610-2ARZ-RL is a dual precision JFET operational amplifier featuring rail-to-rail output. It offers low offset voltage (B grade: 0.4 mV max), low input bias current (5 pA typical), and low noise (7.3 nV/√Hz at 1 kHz). The device operates on dual supplies from ±5 V to ±15 V, with a gain bandwidth product of 16.3 MHz and a slew rate of 61 V/µs at ±15 V. It maintains unity-gain stability without phase reversal and functions within an extended temperature range of −40°C to +125°C.

Feature Summary

• Precision JFET architecture providing very low input bias current and offset voltage for high impedance sensor applications.
• Rail-to-rail output capability ensures maximum dynamic range in single or dual supply configurations.
• No phase reversal when input voltages exceed the common-mode voltage range, maintaining signal integrity.
• Excellent stability with substantial capacitive loads, supporting fast settling times in filter circuits.

Applications

• Medical instruments
• Photodiode amplifiers
• Multipole filters
• Precision current measurement

Procurement Notes

Verify the specific ordering suffix ARZ-RL against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before integration. Cross-reference the B-grade offset voltage limits if precise DC accuracy is critical for the design.

Selection Notes

Select this component for applications requiring high precision combined with wide bandwidth and low noise. The dual configuration simplifies designs needing two matched channels. Consider the rail-to-rail output for maximizing signal swing. Verify that the 8-lead SOIC package fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the ADA4610 family of low noise, precision, rail-to-rail output JFET op amps from Analog Devices. The family includes single (ADA4610-1), dual (ADA4610-2), and quad (ADA4610-4) variants. The ADA4610-2 specifically provides two independent amplifiers in one package, sharing power supply pins.

Replacement Considerations

Official substitutes include other members of the ADA4610 family such as ADA4610-1 or ADA4610-4, depending on channel count needs. Other precision JFET amplifiers like AD8512 may be considered but require verification of pinout and electrical parameter compatibility.
