ADA4610-2ARMZ-RL

Overview

The ADA4610-2ARMZ-RL is a dual precision JFET operational amplifier featuring rail-to-rail output. It operates on dual supplies from ±5 V to ±15 V with a supply current of 1.6 mA per amplifier. Key electrical parameters include a gain bandwidth product of 16.3 MHz, a slew rate of 61 V/µs, and an input offset voltage of 0.4 mV maximum (B grade). The device exhibits low noise with a density of 7.3 nV/√Hz at 1 kHz and maintains stability with capacitive loads.

Feature Summary

• Rail-to-rail output capability ensures maximum dynamic range in single or dual supply configurations.
• JFET input architecture provides extremely low input bias current and low offset voltage for high impedance applications.
• Unity-gain stable design eliminates the need for external compensation components.
• No phase reversal occurs when input voltages exceed the common-mode voltage range.

Applications

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

Procurement Notes

Verify the specific suffix 'RM' corresponds to the MSOP package and '-RL' indicates tape and reel packaging as defined in the manufacturer's ordering guide. Confirm that B-grade specifications apply if low offset voltage is critical for the design. Ensure compatibility with the required operating temperature range of -40°C to +125°C before finalizing procurement.

Selection Notes

Select this component for applications requiring high precision combined with fast settling times and low noise. The dual configuration reduces board space compared to single amplifiers. Consider the B-grade offset voltage limits if strict DC accuracy is required. Verify that the load capacitance requirements are met without oscillation, as the device is optimized for stability with substantial capacitive loads.

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 ADA4610-2 specifically integrates two independent channels in one package, sharing power supply pins while maintaining separate signal paths for differential or dual-channel processing.
