ADA4610-4ARZ

Overview

The ADA4610-4ARZ is a quad precision JFET operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output, low offset voltage (max 1 mV), and low input bias current (5 pA typical). The device 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 a voltage noise density of 7.3 nV/√Hz at 1 kHz. It maintains stability with capacitive loads and offers excellent PSRR and CMRR.

Feature Summary

• Quad configuration with rail-to-rail output capability
• Low input bias current and low offset voltage for high impedance applications
• Unity-gain stable with fast settling time under capacitive loads
• No phase reversal when input voltages exceed the common-mode range

Applications

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

Procurement Notes

Verify the package type matches the design requirements, as the ADA4610-4 is available in 14-lead SOIC and 16-lead LFCSP packages. Confirm that the ordering suffix corresponds to the specific packaging format needed for assembly. Ensure compatibility with the required operating temperature range of -40°C to +125°C.

Selection Notes

Select this component for applications requiring multiple precision channels with low noise and high speed. The quad architecture reduces board space compared to single or dual amplifiers. Consider the 14-lead SOIC or 16-lead LFCSP options based on thermal management needs and PCB layout constraints.

Part Context

The ADA4610-4ARZ belongs to the ADA4610 family of precision JFET op amps, which also includes single (ADA4610-1) and dual (ADA4610-2) variants. This family is designed for high-performance signal processing tasks where low distortion and high accuracy are critical. The quad version provides four independent amplifiers in a single package.

Replacement Considerations

Check datasheets for alternative quad JFET op amps with similar rail-to-rail output and low offset specifications. Verify pinout compatibility if substituting directly into existing designs.
