ADA4610-1ARJZ-RL

Overview

The ADA4610-1ARJZ-RL is a single-channel precision JFET operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output, low offset voltage (max 0.4 mV B grade), 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 1.6 mA per amplifier. The device operates on dual supplies from ±5 V to ±15 V, supports an operating temperature range of -40°C to +125°C, and is housed in a 5-lead SOT-23 package.

Feature Summary

• Rail-to-rail output capability with no phase reversal when input voltages exceed the common-mode range
• Low noise performance including 7.3 nV/√Hz voltage noise density at 1 kHz
• High impedance JFET inputs providing very low input bias current
• Unity-gain stable design suitable for high capacitive loads

Applications

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

Procurement Notes

Verify the specific ordering suffix ARJZ corresponds to the 5-lead SOT-23 package configuration. Confirm that the RL designation indicates tape and reel packaging. Ensure the component meets the required B-grade offset voltage specifications if applicable. Check RoHS compliance status against current manufacturing standards before finalizing procurement.

Selection Notes

Select this component for applications requiring high input impedance combined with low noise and precision DC accuracy. The rail-to-rail output allows for maximum dynamic range in single-supply or dual-supply systems. Consider the SOT-23 package size for space-constrained designs while ensuring thermal management aligns with the specified junction temperature limits.
