Product details
Overview
ADA4851-4WYRUZ-R7 from Analog Devices is a quad, 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 ±5 V or single +3 V to +12 V supplies. Its 0.08% differential gain and 0.09° differential phase support high-fidelity video signal conditioning in infotainment head units.
For engineers reviewing the ADA4851-4WYRUZ-R7 datasheet, ADA4851-4WYRUZ-R7 pinout, ADA4851-4WYRUZ-R7 application, or ADA4851-4WYRUZ-R7 equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification (−40°C to +125°C), 14-lead TSSOP package, quad-channel integration, and verified performance in video reconstruction filters and clock buffer circuits.
Technical Context
The ADA4851-4WYRUZ-R7 implements a voltage-feedback architecture with fully differential input stage and rail-to-rail output stage capable of swinging within 60 mV of either supply rail. It supports stable operation at gains ≥ +1 with 150 Ω load and exhibits < 70 dB crosstalk at 5 MHz between channels.
Its input common-mode range extends 200 mV below the negative rail and up to 2.2 V below the positive rail under ±5 V supply, enabling true single-supply operation. The device includes no internal power-down control - unlike the single-channel ADA4851-1W - and draws 2.9 mA per amplifier at ±5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 130 MHz at G = +1, ±5 V supply - enables baseband video and clock distribution up to 100 MHz without attenuation. |
| Slew Rate | 375 V/μs at G = +2, ±5 V - supports fast transient response for composite video sync pulses and high-speed data buffers. |
| Differential Gain / Phase | 0.08% / 0.09° at NTSC, RL = 150 Ω - meets broadcast-grade video fidelity requirements for automotive display interfaces. |
| Rail-to-Rail Output Swing | Within 60 mV of either rail - maximizes dynamic range in low-voltage systems (e.g., +3.3 V ADAS camera links). |
| Supply Range | 2.7 V to 12 V single or ±5 V dual - accommodates legacy 5 V and modern low-power 3.3 V/2.7 V automotive domains. |
| Operating Temperature | −40°C to +125°C - certified for engine bay and dashboard-mounted electronics per AEC-Q100 Grade 2. |
| Quiescent Current | 2.9 mA per amplifier at ±5 V - balances speed and power for always-on video preprocessing stages. |
Pinout & Package
ADA4851-4WYRUZ-R7 is housed in a 14-lead TSSOP (RU-14) package with exposed pad for thermal enhancement. Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise layout when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | −IN 1 | Inverting input of Channel 1 - referenced to ground or feedback network for inverting configuration. |
| 2 | +IN 1 | Non-inverting input of Channel 1 - accepts single-ended or differential video signals with 200 mV beyond rail capability. |
| 3 | +VS | Positive supply rail - connects to +5 V or +12 V; decoupling capacitor required within 1 cm. |
| 4 | VOUT 2 | Output of Channel 2 - drives 150 Ω video loads directly; supports 66 mA linear output current at 1 MHz. |
| 5 | −IN 2 | Inverting input of Channel 2 - isolated from Channel 1 inputs to maintain >70 dB inter-channel crosstalk. |
| 6 | +IN 2 | Non-inverting input of Channel 2 - identical electrical characteristics to Pin 2 for matched channel performance. |
| 7 | VOUT 1 | Output of Channel 1 - rail-to-rail swing enables full utilization of ADC input range in digitization front-ends. |
| 8 | −IN 4 | Inverting input of Channel 4 - shares same layout symmetry as Pins 1 and 5 for PCB routing consistency. |
| 9 | +IN 4 | Non-inverting input of Channel 4 - supports independent biasing for multi-channel video path alignment. |
| 10 | −VS | Negative supply rail - tied to ground in single-supply mode; must be bypassed near package. |
| 11 | VOUT 3 | Output of Channel 3 - optimized for low THD (< −83 dBc HD2 at 1 MHz) in analog audio preamp paths. |
| 12 | −IN 3 | Inverting input of Channel 3 - electrically isolated to prevent coupling from adjacent high-speed digital traces. |
| 13 | +IN 3 | Non-inverting input of Channel 3 - matches input capacitance (1.2 pF) and resistance (5 MΩ common-mode) across all channels. |
| 14 | VOUT 4 | Output of Channel 4 - capable of sourcing/sinking 125/110 mA short-circuit current for robust fault tolerance. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4851-4YRUZ | Commercial-grade (−40°C to +105°C); lacks AEC-Q100 qualification and extended temp validation. | Not suitable for under-hood or dashboard mounting; limited to cabin-only infotainment modules. | Select only if operating temperature stays ≤ +105°C and automotive qualification is not required. |
| LMH6644MA/NOPB | Higher quiescent current (4.3 mA/ch), lower slew rate (180 V/μs), no AEC-Q100 rating. | Acceptable for non-automotive video but fails thermal and reliability validation for automotive production. | Use where cost sensitivity outweighs automotive compliance; verify thermal margin at +125°C ambient. |

The ADA4851-4WYRUZ-R7 is rated for continuous operation from −40°C to +125°C and is AEC-Q100 Grade 2 qualified. This specification is validated across process corners and lifetime reliability stress tests, ensuring stable parametric performance in engine compartment and dashboard-mounted automotive electronics where ambient temperatures exceed 105°C.
Does ADA4851-4WYRUZ-R7 support power-down functionality?
No, the ADA4851-4WYRUZ-R7 does not include a power-down pin or mode. Power-down capability is exclusive to the single-channel ADA4851-1W variant. The quad ADA4851-4WYRUZ-R7 draws 2.9 mA per amplifier at ±5 V continuously and must be powered off via external supply switching if low-quiescent operation is required.
What load drive capability does ADA4851-4WYRUZ-R7 provide at 150 Ω?
The ADA4851-4WYRUZ-R7 delivers 66 mA linear output current into 150 Ω at 1 MHz with 1% THD, and sustains 125 mA sourcing / 110 mA sinking short-circuit current. This enables direct driving of standard video termination loads without external buffers, preserving signal integrity in broadcast and automotive video routing.
Is ADA4851-4WYRUZ-R7 pin-compatible with other members of the ADA4851 family?
Yes, the ADA4851-4WYRUZ-R7 uses the same 14-lead TSSOP (RU-14) footprint as the standard ADA4851-4YRUZ. Pin functions, spacing, and thermal pad layout are identical - allowing direct substitution in existing designs when upgrading to automotive-grade qualification without PCB revision.
What video standards does ADA4851-4WYRUZ-R7 support out-of-the-box?
The ADA4851-4WYRUZ-R7 is characterized for NTSC video performance with 0.08% differential gain and 0.09° differential phase at RL = 150 Ω. Its 11 MHz 0.1 dB flatness and low harmonic distortion (−83 dBc HD2 at 1 MHz) also support PAL, SECAM, and 720p/1080i component video formats without external compensation networks.
