Product details
Overview
ADA4610-1ARJZ-R2 from Analog Devices is a precision JFET-input single operational amplifier optimized for high-impedance sensor signal conditioning and low-noise current measurement. It delivers 0.4 mV max offset voltage (B grade), 5 pA typical input bias current, 7.30 nV/√Hz voltage noise density at 1 kHz, rail-to-rail output swing, and unity-gain stability - enabling accurate photodiode amplification and medical instrumentation front-ends.
For engineers reviewing the ADA4610-1ARJZ-R2 datasheet, ADA4610-1ARJZ-R2 pinout, ADA4610-1ARJZ-R2 application, or ADA4610-1ARJZ-R2 equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases in precision analog systems, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The ADA4610-1ARJZ-R2 employs a JFET input stage with >10¹³ Ω input resistance and differential input capacitance of 3.1 pF, enabling stable operation with high-Z sources like piezoelectric sensors and photodiodes. Its rail-to-rail output stage supports ±5 V to ±15 V dual-supply operation while delivering ±63 mA short-circuit current and <0.00025% THD + N at 1 kHz.
It achieves 15.4 MHz gain bandwidth product and 21 V/µs slew rate (rising) under ±5 V supply, with 61° phase margin ensuring robust stability into capacitive loads - a key differentiator versus legacy JFET op amps prone to phase reversal or degraded settling with >100 pF load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 0.4 mV max (B grade, 25°C) - enables sub-1 µV error in 100× gain precision current sensing with 100 mΩ shunt. |
| Input Bias Current | 5 pA typical - preserves signal integrity in >1 GΩ source impedance applications such as pH electrodes or photodiode transimpedance stages. |
| Voltage Noise Density | 7.30 nV/√Hz at 1 kHz - ensures <1 µV rms integrated noise in 10 Hz–100 kHz audio and instrumentation bands. |
| Rail-to-Rail Output | Swings to within 100 mV of rails (±5 V supply) - maximizes dynamic range in single-supply or low-headroom systems without level-shifting. |
| Supply Current | 1.70 mA per amplifier (typical, ±5 V) - balances low power with high speed for battery-powered portable test equipment. |
| Unity-Gain Stable | No external compensation required - simplifies layout and reduces BOM count in gain-of-1 buffers and active filters. |
| Operating Temp Range | −40°C to +125°C - qualified for industrial motor control feedback loops and automotive cabin-sensing modules. |
Pinout & Package
ADA4610-1ARJZ-R2 is packaged in a 5-lead SOT-23 (RJ suffix), with exposed pad connected to V− for thermal performance. Pin 1 is OUT; Pin 2 is V−; Pin 3 is +IN; Pin 4 is −IN; Pin 5 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - drives 2 kΩ load to ±4.9 V with <100 mV headroom; requires local 0.1 µF bypass to V−. |
| 2 | V− | Negative supply rail - must be connected to system ground or negative rail; exposed pad (EPAD) ties directly to this pin for thermal dissipation. |
| 3 | +IN | Noninverting input - high-impedance JFET node (>10¹³ Ω); sensitive to PCB leakage; guard ring recommended in high-precision layouts. |
| 4 | −IN | Inverting input - used for transimpedance or difference-amplifier configurations; matched to +IN for CMRR >94 dB. |
| 5 | V+ | Positive supply rail - accepts ±5 V to ±15 V; decoupling capacitor mandatory between V+ and V− near package. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Prevents catastrophic output latch-up when input exceeds common-mode range - critical for overvoltage-tolerant sensor interfaces. |
| Low long-term drift | 5 µV typical (10,000 hrs) - ensures calibration stability in medical diagnostic devices requiring multi-year accuracy retention. |
| Low temperature hysteresis | 8 µV typical - minimizes repeatability error in thermal cycling environments like environmental monitoring stations. |
| Fast settling time | Stable with ≥100 pF capacitive loads - eliminates need for isolation resistors in ADC driver or filter output stages. |
| High PSRR | 104 dB min (±4.5 V to ±18 V) - rejects power supply ripple in mixed-signal systems sharing noisy digital rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision JFET operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8610ARMZ | Higher offset drift (10 µV/°C typ), lower GBP (25 MHz), same 5 pA IB but higher 12 nV/√Hz noise. | Better suited for high-speed, moderate-precision applications; less optimal for sub-µV DC stability requirements. | Select AD8610ARMZ only if bandwidth >20 MHz is prioritized over ultra-low drift and noise. |
| ADA4001-2ARZ | Lower supply current (1.2 mA), wider temp range (−40°C to +150°C), but higher offset (1.5 mV max) and noise (11 nV/√Hz). | Targeted at automotive under-hood sensors where extended temperature tolerance outweighs noise sensitivity. | Choose ADA4001-2ARZ when operating beyond +125°C is required and 0.4 mV offset is not mandatory. |
Compared with AD8610ARMZ and ADA4001-2ARZ, the ADA4610-1ARJZ-R2 offers the lowest combined offset drift and voltage noise in the SOT-23 footprint - making it the preferred choice for DC-critical, high-impedance measurement nodes where long-term calibration stability and sub-microvolt resolution are non-negotiable.

FAQ
What is the maximum supply voltage rating for ADA4610-1ARJZ-R2?
The ADA4610-1ARJZ-R2 has an absolute maximum supply voltage rating of ±18 V, as specified in Table 4 of the Rev. I datasheet. Operation beyond this limit risks permanent damage. For reliable long-term performance, Analog Devices recommends staying within the specified operating range of ±5 V to ±15 V, where all electrical characteristics are guaranteed across temperature.
Does ADA4610-1ARJZ-R2 support single-supply operation?
Yes, ADA4610-1ARJZ-R2 supports single-supply operation by biasing the input common-mode voltage within its specified range (e.g., 2.5 V with 5 V supply). Its rail-to-rail output allows full swing from near ground to near V+, and the input voltage range extends to within 2.5 V of either rail at ±5 V supply - enabling true single-supply configurations in sensor interfaces and portable instrumentation.
Is the exposed pad on ADA4610-1ARJZ-R2 internally connected?
No - the exposed pad on ADA4610-1ARJZ-R2 (SOT-23 package) is not internally connected to any die function. Per Table 7 and Figure 3 of the datasheet, it is electrically isolated and intended solely for thermal conduction. It must be soldered to a PCB copper pour tied to V− to achieve the specified θJA of 219.4°C/W and ensure safe junction temperature under full load.
What is the guaranteed offset voltage specification for ADA4610-1ARJZ-R2 over temperature?
For the ADA4610-1ARJZ-R2 (B grade), the offset voltage is guaranteed at ≤0.8 mV over the full −40°C to +125°C operating temperature range, as stated in Table 2. This is distinct from the 0.4 mV maximum at 25°C and reflects worst-case drift behavior across industrial temperature extremes - critical for uncalibrated field-deployed systems.
Can ADA4610-1ARJZ-R2 drive a 600 Ω load effectively?
Yes - ADA4610-1ARJZ-R2 delivers ±4.89 V output swing into 600 Ω at ±5 V supply (Table 2), with ±63 mA short-circuit current capability. Its output stage maintains linearity and low distortion (<0.00025% THD+N) under this load, making it suitable for driving coaxial cables, ADC reference buffers, and low-impedance transducer outputs without external gain boosting.
