Overview
The ADA4610-2ARZ-R7 is a dual precision JFET operational amplifier featuring rail-to-rail output. It 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 maximum offset voltage of 0.4 mV (B grade), typical input bias current of 5 pA, and voltage noise density of 7.3 nV/√Hz at 1 kHz. The device offers a gain bandwidth product of 16.3 MHz and a slew rate of 61 V/µs. It is housed in an 8-lead SOIC package.
Feature Summary
- Precision JFET architecture providing low input bias current and low offset voltage for high impedance sensor applications.
- Rail-to-rail output capability allowing signal swing close to supply rails without phase reversal issues.
- Low total harmonic distortion plus noise ensuring high fidelity performance in audio and measurement circuits.
Applications
- Medical instruments
- Photodiode amplifiers
- Precision current measurement
- Multipole filters
Procurement Notes
Verify the specific ordering suffix R7 corresponds to tape and reel packaging when sourcing. Confirm that the B grade offset voltage specifications apply if precise DC accuracy is required for the design. Ensure the 8-lead SOIC package dimensions match the target PCB footprint constraints during procurement planning.
Selection Notes
Select this component for designs requiring dual-channel precision amplification with low noise characteristics. The JFET input stage is suitable for high source impedance applications where bias current must be minimized. Verify that the rail-to-rail output range meets the dynamic signal requirements of the downstream circuitry.
Part Context
This part 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 a compact package, sharing core performance metrics like low offset drift and high PSRR across the extended industrial temperature range.
Replacement Considerations
The ADA4610-2BRZ is a pin-compatible alternative available in tube packaging instead of tape and reel. Other family members like the ADA4610-1 or ADA4610-4 offer different channel counts but share similar electrical characteristics.
