ADA4610-2ARMZ-R7

Overview

The ADA4610-2ARMZ-R7 is a dual 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). Key electrical parameters include a gain bandwidth product of 16.3 MHz, a slew rate of 61 V/µs, and a supply current of 1.85 mA per amplifier at ±15 V. The device operates within a supply range of ±5 V to ±15 V and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Precision JFET architecture with rail-to-rail output capability
• Low offset voltage and drift characteristics for high accuracy
• Very low input bias current suitable for high impedance sensors
• No phase reversal when input voltages exceed common-mode range

Applications

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

Procurement Notes

Verify the specific ordering suffix R7 corresponds to tape and reel packaging when sourcing this component. Confirm that the B grade offset voltage specifications apply if precise DC performance is required for the design. Ensure compatibility with the 8-lead MSOP package dimensions during PCB layout planning.

Selection Notes

Select this dual-channel variant when two independent precision amplification paths are needed in a compact footprint. Consider the rail-to-rail output feature for maximizing dynamic range in single-supply or low-voltage dual-supply applications. Evaluate the 16.3 MHz gain bandwidth product against system signal frequency requirements.

Part Context

This component belongs to the ADA4610 family of low noise, precision, rail-to-rail output JFET op amps. The family includes single (ADA4610-1) and quad (ADA4610-4) variants. The ADA4610-2 specifically provides two channels in an 8-lead MSOP package, offering a balance between channel count and board space efficiency.
