ADA4610-2BRZ

Overview

The ADA4610-2BRZ is a dual precision JFET operational amplifier featuring rail-to-rail output. It offers a maximum offset voltage of 0.4 mV and a typical input bias current of 5 pA. The device operates on dual supplies ranging from ±5 V to ±15 V, with an absolute maximum rating of ±18 V. Key dynamic parameters include a gain bandwidth product of 16.3 MHz and a slew rate of 61 V/µs at ±15 V. It provides a power supply rejection ratio of 125 dB and maintains stability with capacitive loads without phase reversal.

Feature Summary

• Features low offset voltage and drift for high DC precision
• Provides rail-to-rail output capability
• Maintains fast settling performance with substantial capacitive loads
• Eliminates output phase reversal when input voltages exceed the common-mode range

Applications

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

Procurement Notes

Verify the B grade designation ensures the specified 0.4 mV maximum offset voltage limit. Confirm the SOIC package suffix matches the required footprint. Check that the operating temperature range covers the intended application environment. Ensure supply voltages remain within the ±18 V absolute maximum ratings.

Selection Notes

Select this component for applications requiring low noise and high impedance sensor interfacing. The dual configuration supports differential signal processing or independent channel usage. Verify that the 79 mA short-circuit current meets load requirements. Consider the extended industrial temperature range for harsh environments.

Part Context

This part belongs to the ADA4610 family of low noise, precision, rail-to-rail output JFET op amps. The -2 suffix indicates a dual amplifier configuration. The BRZ suffix denotes the 8-lead SOIC package with RoHS compliance. Other variants include single and quad configurations in different packages.

Replacement Considerations

ADA4610-2ARZ is a direct pin-compatible alternative in the same SOIC package.
