Product details
Overview
AD8610BRZ-REEL7 from Analog Devices is a precision JFET-input operational amplifier optimized for photodiode amplification, high-speed instrumentation, and fast precision integrators. 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 while operating from ±5 V to ±13 V dual supplies.
For engineers reviewing the AD8610BRZ-REEL7 datasheet, AD8610BRZ-REEL7 pinout, AD8610BRZ-REEL7 application, or AD8610BRZ-REEL7 equivalent, key selection criteria include input bias current stability over temperature (≤10 pA at 25°C, ≤2.5 nA at +125°C), 0.01% settling in ≤600 ns, no phase reversal behavior, and MSOP-8/SOIC-8 package compatibility for space-constrained analog signal chains.
Technical Context
The AD8610BRZ-REEL7 uses Analog Devices' XFCB dielectrically isolated process with N-channel JFET inputs and thin-film resistor trimming, enabling ultralow offset drift (≤1 μV/°C for B-grade) and stable low input bias current across −40°C to +125°C. Its architecture supports unity-gain stability with >1000 pF capacitive loads and rail-to-rail output swing within 1.2 V of supplies into 1 kΩ.
Unlike conventional JFET op amps, the AD8610BRZ-REEL7 maintains <200 pA typical input bias current at +85°C and exhibits no phase reversal when inputs exceed common-mode range - critical for photodiode transimpedance and ATE buffer applications where input overvoltage events occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise Density | 6 nV/√Hz at 1 kHz - enables low-noise photodiode and sensor front-end designs without added filtering overhead |
| Max Input Offset Voltage | 100 μV (B-grade, 25°C) - ensures ≤0.002% gain error in 12-bit+ precision systems without trimming |
| Slew Rate | 50 V/μs (±13 V, RL = 2 kΩ) - supports ≥1.6 MHz full-power bandwidth for 10 VPP signals at 1% THD |
| Gain Bandwidth Product | 25 MHz - allows stable closed-loop gains up to G = +100 at DC–250 kHz with phase margin >45° |
| Input Bias Current | ≤10 pA (25°C), ≤2.5 nA (+125°C) - minimizes leakage-induced errors in high-impedance pH, ion-selective, or piezoelectric sensor interfaces |
| Settling Time to 0.01% | 600 ns (±13 V, 10 V step) - meets timing requirements for fast DAC buffering and multiplexed data acquisition |
| Supply Range | ±5 V to ±13 V - supports legacy industrial rails and high-dynamic-range signal conditioning without level-shifting |
Pinout & Package
AD8610BRZ-REEL7 is packaged in an 8-lead SOIC_N (SOIC-8 narrow-body) surface-mount package per JEDEC MS-012AA, with thermal resistance θJA = 158°C/W. The device is not pin-compatible with MSOP-8 variants (e.g., AD8610ARMZ); SOIC-8 footprint must be used.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null (NC) | No internal connection - must be left unconnected or grounded per layout best practices to avoid parasitic coupling |
| 2 | Inverting Input (−IN) | High-impedance JFET gate node; requires guarded trace routing to prevent leakage-induced offset drift |
| 3 | Noninverting Input (+IN) | Matched to −IN for CMRR >95 dB; symmetric layout critical for achieving specified 137 dB channel separation at 10 kHz |
| 4 | Negative Supply (V−) | Return path for bias current and output stage; low-inductance connection essential for stability with >1 nF loads |
| 5 | Positive Supply (V+) | Power rail for output drive and input stage; decoupling with 0.1 μF ceramic + 10 μF tantalum recommended |
| 6 | Output (OUT) | Capable of ±45 mA drive into 1 kΩ at ±13 V; supports direct interface to SAR ADC drivers and active filters |
| 7 | Null (NC) | No internal connection - floating or grounded per PCB stackup; no effect on performance if left unconnected |
| 8 | Null (NC) | No internal connection - identical to Pin 1 and Pin 7; no routing required |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed operation without polarity inversion when inputs exceed V− or V+ by >1 V - eliminates risk of latch-up in servo feedback paths |
| Stable with >1000 pF load | Enables direct driving of ADC input capacitance and long coaxial cables without external compensation networks |
| Low input bias current over temperature | ≤2.5 nA at +125°C - preserves accuracy in automotive under-hood and industrial oven sensor interfaces |
| High PSRR and CMRR | 110 dB PSRR and 110 dB CMRR at DC - rejects supply ripple and common-mode interference in noisy PLC and motor control environments |
| Fast settling to 0.01% | 600 ns with 10 V step - satisfies throughput requirements for 1 MSPS+ data acquisition systems using multiplexed analog inputs |

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 (3.7 mA vs. 3.0 mA), lower slew rate (27 V/μs), higher input bias current (>100 pA at 25°C) | Limited suitability for high-temperature sensor interfaces due to bias current doubling every 10°C | Select OPA627AP only when ultra-low 1/f noise (<1.5 μV p-p, 0.1–10 Hz) is prioritized over speed and thermal stability |
| ADA4625-1ARZ | Lower noise (4.2 nV/√Hz), wider supply range (±4.5 V to ±18 V), but slower settling (1.2 μs to 0.01%) | Better for wide-supply industrial sensors; less suitable for high-throughput ATE requiring sub-microsecond settling | Choose ADA4625-1ARZ when 0.1–10 Hz noise dominates system error budget and ±18 V operation is needed |
Compared with OPA627AP and ADA4625-1ARZ, AD8610BRZ-REEL7 offers superior thermal stability of input bias current and faster settling-critical for uncooled photodiode arrays and multiplexed data loggers where ambient temperature varies widely.

FAQ
What is the maximum operating temperature range for the AD8610BRZ-REEL7?
The AD8610BRZ-REEL7 is fully specified over the extended industrial temperature range of −40°C to +125°C. Its JFET input stage and XFCB process ensure stable input bias current and offset voltage drift across this range, making it suitable for under-hood automotive and industrial oven applications where passive cooling is unavailable.
Does the AD8610BRZ-REEL7 require external compensation for capacitive loads?
No, the AD8610BRZ-REEL7 is unconditionally stable with capacitive loads exceeding 1000 pF in noninverting unity-gain configuration. It can safely drive up to 10 nF with ±5 V supplies without external compensation, though bandwidth reduction and increased overshoot occur proportionally to load capacitance - verified in Figures 44–45 of the AD8610/AD8620 Rev. F datasheet.
What is the input offset voltage specification for the AD8610BRZ-REEL7?
The AD8610BRZ-REEL7 is the B-grade version, with a maximum input offset voltage of 100 μV at 25°C and 200 μV over the full −40°C to +125°C range. This grade also guarantees offset voltage drift ≤1 μV/°C, enabling high-accuracy DC-coupled measurement systems without periodic recalibration.
Can the AD8610BRZ-REEL7 replace the AD8610ARZ in existing designs?
Yes, AD8610BRZ-REEL7 and AD8610ARZ share identical electrical specifications and SOIC-8 packaging. The "B" suffix denotes tighter offset voltage and drift tolerances versus the "A" grade, and "REEL7" indicates tape-and-reel packaging - both are drop-in replacements in board layouts designed for AD8610ARZ, with improved DC performance.
Is the AD8610BRZ-REEL7 compatible with single-supply operation?
The AD8610BRZ-REEL7 is specified for dual-supply operation from ±5 V to ±13 V and does not support true single-supply use. Its input common-mode range extends to within 2 V of the negative rail and output swings to within 1.2 V of both rails, but proper biasing of inputs and outputs requires symmetric supplies - single-ended configurations require external level-shifting circuitry.
