Product details
Overview
ADA4851-2WYRMZ-R7 from Analog Devices is a dual, rail-to-rail output, voltage-feedback operational amplifier qualified for automotive applications. It delivers 130 MHz −3 dB bandwidth, 375 V/μs slew rate, and 55 ns settling time to 0.1%, operating from 2.7 V to 12 V supplies. Its 0.08% differential gain and 0.09° differential phase support high-fidelity video signal conditioning in automotive infotainment systems.
For engineers reviewing the ADA4851-2WYRMZ-R7 datasheet, ADA4851-2WYRMZ-R7 pinout, ADA4851-2WYRMZ-R7 application, or ADA4851-2WYRMZ-R7 equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification (−40°C to +125°C), MSOP-8 package, dual-channel architecture with independent inputs/outputs, and verified performance under ±5 V, +5 V, and +3 V supply conditions.
Technical Context
The ADA4851-2WYRMZ-R7 implements a voltage-feedback topology optimized for stability with capacitive loads up to 10 pF and drive capability into 150 Ω video loads. Its input stage supports common-mode voltage range extending 200 mV below the negative rail and within 2.2 V of the positive rail, enabling true single-supply operation.
Output stage delivers rail-to-rail swing within 60 mV of either supply rail, linear output current up to 83 mA (±5 V), and low distortion (−83 dBc HD2 / −107 dBc HD3 at 1 MHz). Power-down functionality is not present - only the single-channel ADA4851-1W includes power-down; this dual variant operates continuously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 130 MHz at G = +1, +5 V supply - enables baseband video and clock buffer applications up to ~100 MHz |
| Slew Rate | 375 V/μs at ±5 V - supports fast transient response for 2 V step signals without slewing distortion |
| Settling Time | 55 ns to 0.1% at G = +2, RL = 150 Ω - meets timing-critical video reconstruction and active filter settling requirements |
| Differential Gain / Phase | 0.08% / 0.09° at NTSC, RL = 150 Ω - preserves color fidelity in analog video signal paths |
| Supply Range | 2.7 V to 12 V - supports single-supply (3 V, 5 V) and split-supply (±5 V) configurations without redesign |
| Quiescent Current | 2.8 mA per amplifier at +5 V - balances speed and power for thermally constrained automotive modules |
| Operating Temperature | −40°C to +125°C - AEC-Q100 Grade 2 qualified for under-hood and display module deployment |
Pinout & Package
ADA4851-2WYRMZ-R7 is housed in an 8-lead MSOP (RM-8) package with exposed pad for thermal enhancement. Pin pitch is 0.5 mm; body dimensions are 3.0 mm × 3.0 mm × 0.85 mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Amplifier 1 output | Drives external load; rail-to-rail swing (within 60 mV of rails); capable of sourcing/sinking ≥110 mA short-circuit current |
| 2 - –IN1 | Inverting input, Amp 1 | High-impedance node (0.5 MΩ differential); accepts signals down to −0.2 V with +3 V supply |
| 3 - +IN1 | Non-inverting input, Amp 1 | Matches –IN1 impedance; common-mode range extends to +2.8 V with +5 V supply |
| 4 - –VS | Negative supply rail | Accepts ground (single-supply) or negative voltage (split-supply); absolute max −0.5 V below −VS |
| 5 - +IN2 | Non-inverting input, Amp 2 | Independent of Amp 1; identical specs and biasing; enables dual-path signal processing |
| 6 - –IN2 | Inverting input, Amp 2 | Electrically isolated from Amp 1 inputs; crosstalk −70 dB at 5 MHz confirms channel separation |
| 7 - OUT2 | Amplifier 2 output | Functionally identical to OUT1; no shared output stage - supports independent gain/feedback networks |
| 8 - +VS | Positive supply rail | Accepts 2.7–12 V; PSRR −82 dB (positive) and −81 dB (negative) ensures noise rejection in noisy automotive environments |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 2 qualification | Validated for −40°C to +125°C operation with lifetime reliability testing per automotive stress standards |
| Rail-to-rail output swing | Swings within 60 mV of either supply rail - maximizes dynamic range in low-voltage systems (e.g., 3.3 V ADAS camera interfaces) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4855-2ARMZ | Higher 175 MHz bandwidth, lower 1.8 mA quiescent current, but only rated to +105°C (not AEC-Q100 qualified) | Lacks automotive temperature grade and qualification - unsuitable for under-hood or safety-critical display modules | Select only for industrial or consumer video where extended temperature and qualification are not required |
| LMH6629MA/NOPB | 1.5 GHz bandwidth, 950 V/μs slew rate, but higher 12.5 mA quiescent current and no rail-to-rail output (clips >1 V from rails) | Overqualified for video; excessive bandwidth increases EMI risk and layout sensitivity in cost-sensitive automotive PCBs | Prefer only when >500 MHz small-signal bandwidth is mandatory - otherwise increases BOM and thermal complexity unnecessarily |
Compared with ADA4855-2ARMZ and LMH6629MA/NOPB, ADA4851-2WYRMZ-R7 uniquely balances automotive qualification, video-optimized distortion performance, and power efficiency - making it the optimal choice for cost-sensitive, thermally constrained, and safety-compliant dual-channel video signal paths.

FAQ
What is the operating temperature range for ADA4851-2WYRMZ-R7?
The ADA4851-2WYRMZ-R7 is AEC-Q100 Grade 2 qualified and specified to operate from −40°C to +125°C. This range is validated across all electrical parameters in the datasheet, including bandwidth, distortion, and output swing, making it suitable for engine bay, dashboard, and rear-seat entertainment modules where ambient temperatures exceed standard commercial limits.
Does ADA4851-2WYRMZ-R7 support power-down functionality?
No, ADA4851-2WYRMZ-R7 does not include power-down capability. Power-down is exclusive to the single-channel ADA4851-1W variant (pin 6 labeled POWER DOWN). The ADA4851-2WYRMZ-R7 is a dual-channel device with fixed operation - all pins are signal or supply related, and no control pin is allocated for enable/disable sequencing.
What package type is used for ADA4851-2WYRMZ-R7?
ADA4851-2WYRMZ-R7 uses an 8-lead MSOP (RM-8) package with exposed thermal pad. Dimensions are 3.0 mm × 3.0 mm × 0.85 mm, 0.5 mm lead pitch. This package provides superior thermal performance (θJA = 150°C/W on 4-layer board) versus SOT-23 while maintaining compact footprint for dense automotive PCB layouts.
Can ADA4851-2WYRMZ-R7 drive a 150 Ω video load?
Yes, ADA4851-2WYRMZ-R7 is fully characterized driving 150 Ω loads - all key specs (bandwidth, settling time, differential gain/phase, harmonic distortion) are measured under RL = 150 Ω conditions. It delivers 0.08% differential gain and −83 dBc HD2 at 1 MHz into 150 Ω, meeting SMPTE and ITU-R BT.601 video interface requirements.
Is ADA4851-2WYRMZ-R7 pin-compatible with other members of the ADA4851 family?
No - ADA4851-2WYRMZ-R7 (MSOP-8) is not pin-compatible with ADA4851-1W (SOT-23-6) or ADA4851-4W (TSSOP-14). Pin functions differ across packages: only the dual variant has dedicated +IN2/–IN2/OUT2 pins in positions 5, 6, and 7. Swapping packages requires PCB layout revision and updated decoupling.
