Product details
Overview
AD8510BRZ-REEL7 from Analog Devices is a single-channel, precision JFET-input operational amplifier optimized for high-impedance sensor signal conditioning and low-noise current measurement. It delivers 400 μV max offset voltage, 8 nV/√Hz voltage noise at 1 kHz, 20 V/μs slew rate, and 0.1% settling in 500 ns - enabling accurate buffering of 12-bit DAC outputs in medical instrumentation and automated test equipment.
For engineers reviewing the AD8510BRZ-REEL7 datasheet, AD8510BRZ-REEL7 pinout, AD8510BRZ-REEL7 application, or AD8510BRZ-REEL7 equivalent, key selection criteria include input bias current (25 pA typ at ±15 V), unity-gain stability with capacitive loads up to 1000 pF, absence of output phase reversal, and operation across −40°C to +125°C.
Technical Context
The AD8510BRZ-REEL7 employs a JFET input stage to achieve ultra-low input bias current (25 pA typical) and low input current noise, critical for photodiode and shunt-based current sensing. Its rail-to-rail output swing (±4.9 V min into 2 kΩ at ±5 V supplies) and fast overload recovery (<200 ns) support transient-resilient precision signal chains.
Unlike legacy JFET op amps, it eliminates output phase reversal beyond common-mode limits and maintains stability driving ≥500 pF loads without external compensation - verified by 52° phase margin at ±15 V with 2.5 kΩ || 20 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage (B Grade) | 0.4 mV max - ensures ≤0.01% error in 40 V full-scale precision current sensing |
| Input Bias Current | 25 pA typical at ±15 V - enables use with >1 GΩ source impedances without significant DC error |
| Voltage Noise Density | 8 nV/√Hz at 1 kHz - supports sub-μV resolution in audio and sensor front-ends |
| Slew Rate | 20 V/μs - allows clean amplification of 1 MHz square waves with <1% distortion |
| Gain Bandwidth Product | 8 MHz - supports stable closed-loop gain ≥10 at 500 kHz |
| Settling Time | 500 ns to 0.1% - matches or exceeds 12-bit DAC settling requirements |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood applications |
Pinout & Package
AD8510BRZ-REEL7 is housed in an 8-lead SOIC_N (R suffix) package, measuring 4.9 mm × 3.9 mm × 1.75 mm, with standard JEDEC MS-012AC footprint and RoHS-compliant matte tin lead finish.

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 |
|---|---|---|---|
| OPA140AIDR | Lower input bias current (0.5 pA), higher GBP (11 MHz), but higher voltage noise (11 nV/√Hz) | Better for femtoamp-level photodiode currents; less optimal for low-noise audio due to higher en | Select OPA140AIDR when input bias current dominates error budget; AD8510BRZ-REEL7 preferred for balanced noise/bias performance |
| LT1782CS5#TRMPBF | Single-supply only (2.7–36 V), lower quiescent current (0.9 mA), but higher offset (600 μV max) and slower settling (1.2 μs) | Suitable for battery-powered portable sensors where supply headroom is constrained | Choose LT1782CS5#TRMPBF for single-supply, low-power designs; AD8510BRZ-REEL7 remains optimal for dual-supply precision systems |
Compared with OPA140AIDR and LT1782CS5#TRMPBF, AD8510BRZ-REEL7 uniquely balances ultra-low input bias current (25 pA), low voltage noise (8 nV/√Hz), and fast settling (500 ns) in a dual-supply architecture - making it the most suitable choice for high-accuracy, wide-bandwidth sensor interfaces requiring both dc precision and dynamic fidelity.

FAQ
What is the maximum capacitive load the AD8510BRZ-REEL7 can drive without oscillation?
The AD8510BRZ-REEL7 is unconditionally stable and drives up to 1000 pF in unity-gain configuration without oscillation. Test data confirms stable operation with 500 pF loads using worst-case layout, and snubber networks (e.g., 100 Ω + 1 nF) reduce overshoot from 55% to <3% for loads ≥500 pF. This capability makes AD8510BRZ-REEL7 ideal for direct interfacing with ADC input filters and long cables.
Does the AD8510BRZ-REEL7 exhibit output phase reversal when inputs exceed the supply rails?
No, the AD8510BRZ-REEL7 does not suffer from output phase reversal - a known failure mode in older JFET op amps. Its internal protection circuitry ensures polarity integrity even when input voltages exceed the ±15 V supply rails by up to 0.7 V. This behavior is confirmed in Figure 40 of the Rev. K datasheet and eliminates risk of system lockup in overvoltage conditions.
What is the typical input bias current of the AD8510BRZ-REEL7 at ±5 V supply?
At ±5 V supply and 25°C, the AD8510BRZ-REEL7 exhibits 21 pA typical input bias current (IB), per Table 1 of the Rev. K datasheet. This value increases to 75 pA maximum at 25°C and rises to 0.7 nA maximum across −40°C to +85°C. The ultra-low IB enables high-impedance sensor interfacing without significant DC error.
Can the AD8510BRZ-REEL7 operate from a single 10 V supply?
Yes, the AD8510BRZ-REEL7 supports single-supply operation with total supply voltage ranging from 10 V to 30 V (±5 V to ±15 V dual equivalent). When powered from +10 V and GND, its input common-mode range extends from −2.0 V to +2.5 V relative to GND, and output swings from ~0.7 V to ~9.3 V into 10 kΩ. Full specifications are guaranteed only across the dual-supply range, but functional operation is validated at 10 V single-ended.
What package type and reel size is used for the AD8510BRZ-REEL7?
The AD8510BRZ-REEL7 uses an 8-lead narrow SOIC_N (SOIC-8) package per JEDEC MS-012AC, with body dimensions 4.9 mm × 3.9 mm × 1.75 mm. It is supplied in tape-and-reel format per EIA-481-D standard, with 2500 units per reel - consistent with the "REEL7" suffix designation and confirmed in the Ordering Guide on page 21 of Rev. K.
