Overview
The ADA4610-1BRZ is a single-channel precision JFET operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output, low offset voltage (B grade: max 0.4 mV), and low input bias current (5 pA typical). Operating on dual supplies from ±5 V to ±15 V, it offers a gain bandwidth product of 16.3 MHz and a slew rate of 25 V/µs rising at ±15 V. The device maintains unity-gain stability without phase reversal and operates within an extended temperature range of -40°C to +125°C.
Feature Summary
- Precision JFET architecture with rail-to-rail output capability
- Low offset voltage and drift characteristics for high accuracy
- Very low input bias current suitable for high impedance sensors
- No phase reversal when input voltages exceed common-mode range
Applications
- Instrumentation systems
- Medical instruments
- Multipole filters
- Precision current measurement
- Photodiode amplifiers
Procurement Notes
Verify the specific B-grade offset voltage specifications against the latest official datasheet revision before integration. Confirm that the 8-lead SOIC package dimensions match the target PCB footprint requirements. Ensure supply voltage limits remain within the absolute maximum ratings to prevent permanent damage.
Selection Notes
Select this component for applications requiring high DC precision combined with low noise performance. The B-grade variant provides tighter offset voltage tolerances compared to standard grades. Consider the rail-to-rail output swing when designing circuits near the supply rails. Verify thermal resistance values if operating in enclosed environments.
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), dual (ADA4610-2), and quad (ADA4610-4) configurations. The BRZ suffix indicates an 8-lead SOIC package with RoHS compliance.
Replacement Considerations
Check for direct pin-compatible alternatives within the AD851x or AD86xx series if sourcing constraints exist. Verify that any substitute maintains the required B-grade offset voltage specifications and rail-to-rail output capabilities.
