ADA4610-1ARZ-RL

Overview

The ADA4610-1ARZ-RL is a single-channel precision JFET operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output, low offset voltage (max 0.4 mV B grade), and low input bias current (typical 5 pA). The device operates on dual supplies from ±5 V to ±15 V. Key electrical parameters include a gain bandwidth product of 16.3 MHz, a slew rate of 25 V/µs rising and 61 V/µs falling, and a supply current of 1.6 mA per amplifier. It is housed in an 8-lead SOIC package.

Feature Summary

• Precision JFET architecture with very low input bias current and low offset voltage drift for high impedance sensor applications.
• Rail-to-rail output capability ensuring maximum dynamic range without phase reversal when input voltages exceed the common-mode range.
• Fast settling time and stability under substantial capacitive loads, suitable for high-performance filter designs.
• Low total harmonic distortion plus noise and low voltage noise density for audio and precision measurement circuits.

Applications

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

Procurement Notes

Verify the specific ordering suffix ARZ-RL against the manufacturer's official documentation to confirm the package type, temperature range, and reel quantity specifications. Ensure compatibility with the intended PCB footprint and reflow soldering profile for the 8-lead SOIC package. Cross-reference the part number with the latest datasheet revision to confirm any updates to electrical characteristics or pin configurations.

Selection Notes

Select this component for applications requiring high DC precision combined with low noise and fast transient response. The JFET input stage provides extremely low input bias current, making it ideal for high-impedance sources. Consider the rail-to-rail output feature if maximizing signal swing near the supply rails is critical. Verify that the operating temperature range of -40°C to +125°C meets the environmental requirements of the target system.

Part Context

The ADA4610-1 is part of the ADA4610 family, which includes dual (ADA4610-2) and quad (ADA4610-4) variants. This family shares similar performance characteristics, including low noise, precision, and rail-to-rail output capabilities. The single-channel configuration offers design flexibility for space-constrained applications while maintaining the high performance standards of the broader series.
