ADA4610-2ACPZ-RL

Overview

The ADA4610-2ACPZ-RL is a dual precision JFET operational amplifier featuring rail-to-rail output. It operates on dual supplies from ±5 V to ±15 V with an operating temperature range of −40°C to +125°C. Key electrical parameters include a maximum offset voltage of 0.4 mV (B grade), typical input bias current of 5 pA, and supply current of 1.6 mA per amplifier at ±15 V. Dynamic performance includes a gain bandwidth product of 16.3 MHz, slew rate of 61 V/µs, and unity-gain crossover frequency of 9.3 MHz. Noise characteristics feature 7.30 nV/√Hz voltage noise density at 1 kHz and 0.45 µV p-p low-frequency noise.

Feature Summary

• Precision JFET architecture providing low input bias current and low offset voltage for high impedance sensor applications.
• Rail-to-rail output capability ensures maximum dynamic range in single or dual supply configurations.
• Unity-gain stable design with no phase reversal when input voltages exceed the common-mode range.
• Fast settling time and stability under substantial capacitive loads suitable for high-performance filtering.

Applications

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

Procurement Notes

Verify the specific package suffix 'CP' corresponds to the 8-Lead LFCSP form factor required for the PCB layout. Confirm that the '-RL' suffix indicates tape and reel packaging rather than tube. Ensure the B grade offset voltage specifications are acceptable for the intended circuit accuracy requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring low noise and high precision with JFET inputs. The dual configuration reduces board space compared to single amplifiers. Verify that the ±5 V to ±15 V supply range matches the system power rails. Consider the thermal resistance of the LFCSP package if high ambient temperatures are expected.

Part Context

This device 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 independent channels in one package, sharing the same core electrical characteristics and pinout compatibility across different package options like SOIC and MSOP.

FAQ

Does the ADA4610-2 suffer from output phase reversal?

No, unlike many older JFET amplifiers, the ADA4610-2 does not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range.

What is the maximum supply voltage for this device?

The absolute maximum supply voltage rating is ±18 V. However, standard operation is specified for dual supplies ranging from ±5 V to ±15 V.
