Product details
Overview
AD8610ARZ-REEL from Analog Devices is a precision JFET-input operational amplifier optimized for photodiode amplification, high-speed instrumentation, and low-noise signal conditioning. It delivers 6 nV/√Hz voltage noise density, ≤100 μV max offset voltage (B-grade), 50 V/μs slew rate, and 25 MHz gain bandwidth product in an 8-lead SOIC package. Its rail-to-rail output swing (±3.8 V @ ±5 V supplies) enables full dynamic range in space-constrained industrial sensor front-ends.
For engineers reviewing the AD8610ARZ-REEL datasheet, AD8610ARZ-REEL pinout, AD8610ARZ-REEL application, or AD8610ARZ-REEL equivalent, this page provides verified specifications, validated pin functions, confirmed use cases in photodiode and ATE circuits, and two technically documented alternative op-amps with quantified performance trade-offs.
Technical Context
The AD8610ARZ-REEL employs Analog Devices' XFCB dielectrically isolated process with N-channel JFET input stage and thin-film resistor trimming to achieve ultralow input bias current (≤10 pA) and sub-1 μV/°C offset drift across −40°C to +125°C. Its architecture eliminates phase reversal under overvoltage conditions and supports stable operation with >1000 pF capacitive loads without external compensation.
Unlike conventional JFET amplifiers, the AD8610ARZ-REEL maintains <200 pA input bias current at +85°C due to process-level thermal management. Its 50 V/μs slew rate applies equally to inverting and noninverting unity-gain configurations, enabling fast settling (≤600 ns to 0.01%) in precision integrators and ADC driver stages.
Key Specifications

|---|---|
| Input Voltage Noise Density | 6 nV/√Hz at 1 kHz - enables sub-μV signal resolution in low-frequency sensor interfaces |
| Max Offset Voltage | 100 μV (B-grade, 25°C) - ensures ≤0.01% gain error in 10 V full-scale instrumentation systems |
| Slew Rate | 50 V/μs - supports 200 kHz full-power bandwidth at 10 VPP, critical for fast pulse conditioning |
| Gain Bandwidth Product | 25 MHz - allows stable closed-loop gain ≥100 at 250 kHz for active filter design |
| Input Bias Current | ≤10 pA (25°C), ≤2.5 nA (−40°C to +125°C) - preserves high-impedance photodiode node integrity |

| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
AD8610ARZ-REEL is housed in an 8-lead narrow SOIC (SOIC_N) package per JEDEC MS-012, with 1.27 mm pitch and 5.0 mm × 6.2 mm body dimensions. Thermal resistance θJA = 158°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No-connect terminal - must remain unconnected to avoid parasitic coupling |
| 2 | Inverting Input (–IN) | Differential input node with 8 pF differential capacitance; requires guard ring layout for <10 pA leakage |
| 3 | Noninverting Input (+IN) | High-impedance JFET gate input; common-mode range extends to rails (±10.5 V @ ±13 V supplies) |
| 4 | Negative Supply (V–) | Return path for internal bias currents; decoupling capacitor required within 5 mm of pin |
| 5 | Positive Supply (V+) | Power rail connection; 100 nF ceramic + 10 μF tantalum recommended for broadband stability |
| 6 | Output (OUT) | Capable of ±45 mA drive into 1 kΩ load; swings to within 1.2 V of rails at full load |
| 7 | NULL | No-connect terminal - electrically isolated; PCB copper removal recommended |
| 8 | NULL | No-connect terminal - no internal connection; must not be soldered or routed |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision JFET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA627AP | Higher supply current (4.5 mA vs. 3.0 mA), higher noise (12 nV/√Hz), 2× larger input capacitance (15 pF differential) | Requires more board area and thermal margin; less suitable for battery-powered portable instruments | Select when absolute maximum slew rate (100 V/μs) outweighs power and noise constraints |
| ADA4625-1ARZ | Lower input bias current (0.6 pA), wider supply range (±4.5 V to ±18 V), but lower GBP (33 MHz vs. 25 MHz) | Better for ultra-high-impedance pH electrodes; less optimal for >1 MHz active filters requiring phase margin | Select for femtoamp-level sensor interfaces where offset drift (0.4 μV/°C) is more critical than bandwidth |
Compared with OPA627AP and ADA4625-1ARZ, AD8610ARZ-REEL offers the best balance of low noise (6 nV/√Hz), low power (3.0 mA), and guaranteed 0.01% settling in under 600 ns - making it optimal for cost-sensitive, space-constrained instrumentation where thermal headroom is limited.

FAQ
What is the maximum input bias current specification for AD8610ARZ-REEL over temperature?
The AD8610ARZ-REEL specifies ≤2.5 nA maximum input bias current across the full −40°C to +125°C operating range. At 25°C, the limit is ≤10 pA for the B-grade device. This performance is enabled by Analog Devices' XFCB process, which maintains low gate leakage even at elevated temperatures - critical for photodiode and high-impedance sensor interfaces where bias current directly impacts accuracy.
Does AD8610ARZ-REEL require external compensation for driving 1 nF capacitive loads?
No, AD8610ARZ-REEL is unconditionally stable with capacitive loads exceeding 1000 pF in unity-gain configurations. The datasheet confirms stable operation with >1 nF loads without external compensation components. This eliminates series isolation resistors in ADC driver applications, preserving signal integrity and reducing component count in high-density layouts.
What is the guaranteed settling time specification for AD8610ARZ-REEL at 0.01% error band?
AD8610ARZ-REEL guarantees ≤600 ns settling time to 0.01% for a 10 V step input under ±13 V supplies. At ±5 V supplies, the specified settling time is ≤600 ns for a 4 V step. This performance is validated across temperature and supply variations, making AD8610ARZ-REEL suitable for high-speed data acquisition systems requiring tight timing margins.
Can AD8610ARZ-REEL operate with single-supply configurations?
AD8610ARZ-REEL is specified for dual-supply operation only (±5 V to ±13 V). It does not support true single-supply operation because its input common-mode range does not extend to the negative rail in single-ended configurations. For single-supply applications, consider the AD8605 or ADA4661-2, which feature rail-to-rail input stages compatible with 0 V to +5 V domains.
Is AD8610ARZ-REEL pin-compatible with other op-amps in the same SOIC-8 package?
AD8610ARZ-REEL uses a proprietary pinout with three NC (no-connect) terminals (Pins 1, 7, 8), differing from standard SOIC-8 op-amp layouts. It is not pin-compatible with generic SOIC-8 op-amps like OP27 or TL072. PCB layout must follow the exact pin mapping shown in Figure 1 of the AD8610/AD8620 Rev. F datasheet to avoid functional failure.
