Product details
Overview
AD8652ARMZ from Analog Devices is a dual-channel, rail-to-rail input/output precision CMOS operational amplifier optimized for high-speed, low-noise signal conditioning in single-supply systems. It delivers 50 MHz gain bandwidth, 41 V/μs slew rate, and 4.5 nV/√Hz voltage noise density at 100 kHz, with 100 μV typical offset voltage over full common-mode range - enabling accurate amplification in laser driver feedback loops and high-resolution ADC front-ends.
For engineers reviewing the AD8652ARMZ datasheet, AD8652ARMZ pinout, AD8652ARMZ application, or AD8652ARMZ equivalent, this page provides verified technical context, package-specific pin definitions, real-world application mappings, and two validated alternative parts - all grounded in Rev. D datasheet specifications and official Analog Devices characterization data.
Technical Context
The AD8652ARMZ implements a dual-channel voltage-feedback architecture with independent NMOS/PMOS parallel input stages, enabling true rail-to-rail input operation across –0.1 V to +5.1 V (at 5 V supply) and eliminating phase reversal within supply rails. Its DigiTrim® post-package trimming corrects offset voltage across the entire common-mode range, guaranteeing 77–100 dB CMRR and <1.4 mV max offset over –40°C to +125°C.
Output stage uses complementary NMOS/PMOS common-source pairs delivering rail-to-rail swing: VOH = 4.97 V and VOL = 30 mV at 250 µA load, with 40 mA continuous output current capability and 0.1 µs overload recovery from negative rail. Dynamic performance is stabilized by 6 pF differential input capacitance and 9 pF common-mode capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - supports stable unity-gain buffer or G = 10 closed-loop configurations up to 5 MHz without peaking. |
| Slew Rate | 41 V/μs - enables clean 2 V step response settling to 0.01% in 0.2 μs, critical for video line driving and DAC reconstruction. |
| Voltage Noise Density | 4.5 nV/√Hz at 100 kHz - ensures <0.0006% THD+N in 1 kHz, 2 Vp-p audio and instrumentation paths. |
| Input Offset Voltage | 90 μV typical, ≤1.4 mV max over –40°C to +125°C - maintains DC accuracy in PA control loops and optical transimpedance amplifiers. |
| Supply Range | 2.7 V to 5.5 V - allows direct interface with 3.3 V and 5 V logic domains without level-shifting in portable comms systems. |
| Input Bias Current | 1 pA typical - preserves high-impedance sensor node integrity in photodiode preamps and medical electrode interfaces. |
| CMRR | 77–100 dB over full common-mode range - suppresses supply-coupled interference in single-supply broadband receivers. |
Pinout & Package
AD8652ARMZ is housed in an 8-lead MSOP (RM-8) package with exposed pad (thermal pad not electrically connected). Pin 1 is marked via dot; pins are numbered counterclockwise. NC pins are internally unconnected and must remain floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 40 mA; rail-to-rail swing enables full dynamic range utilization in 3.3 V systems. |
| 2 | –IN A | Inverting input of Channel A - accepts signals from –0.1 V to +5.1 V; matched to +IN A for precision differential gain. |
| 3 | +IN A | Non-inverting input of Channel A - same common-mode range as –IN A; used for unity-gain buffers and reference followers. |
| 4 | V– | Negative supply rail - tied to ground in single-supply operation; must be decoupled with 0.1 µF ceramic capacitor. |
| 5 | +IN B | Non-inverting input of Channel B - electrically isolated from Channel A; supports dual-path signal processing. |
| 6 | –IN B | Inverting input of Channel B - identical specs to –IN A; enables matched dual-opamp topologies like instrumentation amps. |
| 7 | OUT B | Amplifier B output - independent output stage; shares V+ and V– rails but no crosstalk beyond specified channel separation. |
| 8 | V+ | Positive supply rail - accepts 2.7–5.5 V; PSRR ≥74 dB ensures immunity to digital supply noise in mixed-signal PCBs. |
Key Features
| Feature | Design Value |
|---|---|
| DigiTrim® post-package offset correction | Guarantees 90 μV typical VOS and <4 μV/°C drift across full temperature and common-mode range - eliminates system calibration for laser bias control. |
| Rail-to-rail input stage (NMOS + PMOS parallel) | Extends VCM to –0.1 V and +5.1 V at 5 V supply - enables direct sensing of signals near ground or VCC in battery-powered optical modules. |
| Rail-to-rail output stage (complementary MOS) | Delivers 30 mV VOL and 4.97 V VOH at 250 µA - preserves >99% of 5 V full-scale range for 12-bit+ ADC drivers. |
| Low 4.5 nV/√Hz noise at 100 kHz | Enables <1 LSB error in 16-bit, 1 MSPS SAR ADC front-ends with 2 Vp-p input - critical for ultrasound and test equipment. |
| 0.1 µs negative-rail overload recovery | Prevents latch-up and distortion during transient overloads in RF power amplifier control loops - verified per Figure 31, Rev. D. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2350EA/250 | 36 V/μs slew rate, 38 MHz GBW, 7 nV/√Hz noise, SOIC-8 only | Lower speed/noise margin; less suitable for >5 MSPS ADC drivers or 10 Gbps laser bias loops | Preferred where cost sensitivity outweighs 50 MHz/4.5 nV/√Hz requirement and SOIC-8 footprint is mandatory |
| ADA4898-2 | 1000 V/μs slew rate, 270 MHz GBW, 1 nV/√Hz noise, ±5 V min supply | Requires dual supply; over-spec'd for 5 V single-supply laser/ADC use cases; higher quiescent current (10 mA/channel) | Selected only when >100 MHz bandwidth or sub-2 nV/√Hz noise is required - not drop-in compatible due to supply and layout constraints |
Compared with OPA2350EA/250 and ADA4898-2, AD8652ARMZ uniquely balances 50 MHz bandwidth, 4.5 nV/√Hz noise, rail-to-rail I/O, and 2.7–5.5 V single-supply operation in MSOP-8 - making it optimal for space-constrained, battery-powered optical and data acquisition systems where thermal and voltage headroom are limited.

FAQ
What is the maximum operating temperature range for AD8652ARMZ?
AD8652ARMZ is specified for continuous operation from –40°C to +125°C, with guaranteed performance including offset voltage ≤1.4 mV, CMRR ≥73 dB, and supply current ≤23.5 mA across this full extended industrial range - validated per Table 1 and Table 2 in Rev. D datasheet.
Does AD8652ARMZ support true rail-to-rail input at 2.7 V supply?
Yes, AD8652ARMZ supports rail-to-rail input with VCM from –0.1 V to +2.8 V at 2.7 V supply, enabling direct interfacing with sensors and DACs operating near ground or VCC - confirmed in Table 1, "Input Voltage Range" specification.
What is the recommended power supply bypassing for AD8652ARMZ?
Per Analog Devices Rev. D datasheet Section "Layout, Grounding, and Bypassing Considerations", AD8652ARMZ requires a 0.1 µF X7R/NPO ceramic capacitor placed as close as possible to each V+ and V– pin, plus a bulk 4.7 µF tantalum capacitor at the board's main supply entry point - minimizing high-frequency supply impedance.
Can AD8652ARMZ drive 600 Ω loads at 1 kHz without exceeding THD+N spec?
Yes, AD8652ARMZ achieves 0.0006% THD+N at 1 kHz with 2 Vp-p output into 600 Ω load - directly specified in Table 1 "Dynamic Performance" section - making it suitable for professional audio line drivers and precision test signal generation.
Is AD8652ARMZ pin-compatible with AD8651ARMZ?
No, AD8652ARMZ (dual-channel) and AD8651ARMZ (single-channel) share the same MSOP-8 pinout for their respective channels, but AD8651ARMZ has unused pins repurposed (e.g., Pin 5 = NC vs. AD8652ARMZ Pin 5 = +IN B), so they are not pin-compatible replacements - verified in Figures 1–4 of Rev. D datasheet.
