ADA4610-1ARJZ-R7

Overview

The ADA4610-1ARJZ-R7 is a single-channel precision JFET operational amplifier featuring rail-to-rail output. It operates on dual supplies from ±5 V to ±15 V (9 V to 30 V total). 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 1.8 mV maximum. The device draws 1.6 mA supply current per amplifier and provides 79 mA output current. It maintains stability with capacitive loads and exhibits no phase reversal.

Feature Summary

• Features low input bias current and low offset voltage for high impedance sensor amplification.
• Provides rail-to-rail output capability without phase reversal when input voltages exceed the common-mode range.
• Maintains fast settling performance even with substantial capacitive loads.

Applications

• Medical instruments
• Precision current measurement
• Photodiode amplifiers

Procurement Notes

Verify the specific package suffix 'RJ' corresponds to the 5-lead SOT-23 form factor required for the design. Confirm that the '-R7' suffix indicates tape and reel packaging suitable for automated assembly processes. Ensure the component meets the extended industrial temperature range specifications defined in the datasheet.

Selection Notes

Select this component for applications requiring low noise and high precision in a compact surface-mount footprint. The JFET input stage offers superior bias current characteristics compared to CMOS alternatives. Consider the rail-to-rail output swing if signal dynamic range near the supply rails is critical for the system architecture.

Part Context

This part belongs to the ADA4610 family of low noise, precision JFET op amps manufactured by Analog Devices. The family includes single, dual, and quad variants designed for high-performance analog signal processing. The ADA4610-1 specifically denotes the single-channel configuration within this series.

Replacement Considerations

The AD820 is identified as a predecessor device in the manufacturer's documentation. Verify pin compatibility and electrical parameter alignment before substituting older JFET amplifiers in existing designs.
