Product details
Overview
ADA4851-1WYRJZ-R7 from Analog Devices is a single-channel, 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 ADA4851-1WYRJZ-R7 datasheet, ADA4851-1WYRJZ-R7 pinout, ADA4851-1WYRJZ-R7 application, or ADA4851-1WYRJZ-R7 equivalent, key selection considerations include its automotive-grade temperature range (−40°C to +125°C), power-down capability, 60 mV rail-to-rail output swing, and verified performance at ±5 V, +5 V, and +3 V supplies.
Technical Context
The ADA4851-1WYRJZ-R7 employs a voltage-feedback architecture optimized for high-speed, low-distortion operation. It supports closed-loop gains from +1 to +10 with stable response into 150 Ω loads and tolerates up to 10 pF capacitive load without peaking-verified across supply voltages and temperatures.
Its input stage operates with common-mode range extending 200 mV below the negative rail and within 2.2 V of the positive rail; the rail-to-rail output stage delivers linear current up to 83 mA (±5 V) while maintaining <0.1 dB flatness to 11 MHz at G = +2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 130 MHz at G = +1, +5 V supply - enables wideband video and clock buffer applications without gain-dependent bandwidth collapse. |
| Slew Rate | 375 V/μs at ±5 V, G = +2 - supports fast transient response for 2 V step signals with minimal distortion. |
| Settling Time | 55 ns to 0.1% at G = +2, RL = 150 Ω - ensures accurate pulse fidelity in active filters and reconstruction stages. |
| Differential Gain / Phase | 0.08% / 0.09° at NTSC, G = +2 - meets broadcast-grade video linearity requirements for automotive display interfaces. |
| Rail-to-Rail Output Swing | Within 60 mV of either supply rail - maximizes dynamic range in single-supply 3.3 V or 5 V systems. |
| Quiescent Current | 2.8 mA per amplifier at +5 V - balances speed and power efficiency for always-on automotive subsystems. |
| Operating Temperature | −40°C to +125°C - certified for under-hood and dashboard-mounted electronics per AEC-Q100. |
Pinout & Package
ADA4851-1WYRJZ-R7 is housed in a 6-lead SOT-23 package (RJ-6), optimized for space-constrained automotive PCB layouts. Thermal resistance θJA is 170°C/W on a standard 4-layer JEDEC board.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Amplifier output node; drives 150 Ω video loads or high-speed ADC inputs with minimal droop. |
| 2 | −IN | Inverting input; accepts differential or single-ended signals with 0.5 MΩ differential input resistance. |
| 3 | +IN | Non-inverting input; supports common-mode range from −0.2 V to +2.8 V at +5 V supply. |
| 4 | −VS | Negative supply terminal; connects to ground in single-supply mode or −5 V in dual-supply configurations. |
| 5 | +VS | Positive supply terminal; operates from 2.7 V to 12 V, enabling direct connection to automotive 5 V or 3.3 V rails. |
| 6 | POWER DOWN | Digital control input; pulls low (<1.1 V) to reduce quiescent current to 0.3 mA, enabling system-level power gating. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 compliant (−40°C to +125°C), with production test coverage for parametric stability over lifetime. |
| Power-down mode | Reduces supply current to 0.3 mA while retaining fast 50 ns turn-on time-critical for wake-on-event video subsystems. |
| Video-optimized linearity | 0.1 dB flatness to 11 MHz and <−80 dBc HD2/HD3 at 1 MHz ensure minimal color error in RGB/YUV path reconstruction. |
| Rail-to-rail output drive | Swings to within 60 mV of both rails at full load, preserving >95% of available voltage headroom in 3.3 V systems. |
| Supply flexibility | Specified across +3 V, +5 V, and ±5 V-eliminates need for level-shifting in mixed-voltage automotive ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4851-1YRJZ-R7 | Commercial-grade version; same electrical specs but rated only to +105°C (not AEC-Q100). | Limited to non-automotive industrial or consumer video where extended temperature is not required. | Select when cost sensitivity outweighs automotive qualification needs and ambient temperature stays ≤+105°C. |
| LMH6629MA/NOPB | Higher 1.5 GHz GBW but no power-down pin; 12 mA quiescent current vs. 2.8 mA; not AEC-Q100 qualified. | Better for ultra-wideband lab equipment; unsuitable for automotive power-gated systems. | Choose only if bandwidth >500 MHz is mandatory and automotive qualification is irrelevant. |
Compared with ADA4851-1YRJZ-R7, the ADA4851-1WYRJZ-R7 adds guaranteed −40°C to +125°C operation and AEC-Q100 stress testing; compared with LMH6629MA/NOPB, it trades raw bandwidth for automotive compliance, lower power, and integrated power management-making it the sole fit for safety-critical vehicle display systems.

FAQ
What is the maximum operating supply voltage for ADA4851-1WYRJZ-R7?
The ADA4851-1WYRJZ-R7 supports a total supply voltage range of 2.7 V to 12 V, with absolute maximum ratings specifying 12.6 V across +VS and −VS pins. Operation at ±5 V (10 V total), +5 V single-supply, or +3.3 V is fully characterized and supported across the full −40°C to +125°C automotive temperature range.
Does ADA4851-1WYRJZ-R7 support true single-supply operation with input signals near ground?
Yes. The ADA4851-1WYRJZ-R7 features an input common-mode voltage range extending 200 mV below the negative rail (e.g., −0.2 V at +3 V supply), allowing direct interface with ground-referenced video sources or sensor outputs without level shifting-verified in the +3 V supply specifications table.
How does the power-down function behave on ADA4851-1WYRJZ-R7?
The POWER DOWN pin (Pin 6) disables the amplifier core when pulled below 1.1 V, reducing quiescent current to 0.3 mA. Turn-on occurs within 50 ns when the pin rises above 1.6 V. This behavior is tested and specified across −40°C to +125°C, making it reliable for automotive sleep/wake protocols.
Is ADA4851-1WYRJZ-R7 pin-compatible with other members of the ADA4851 family?
No. ADA4851-1WYRJZ-R7 uses a 6-lead SOT-23 (RJ-6) package, while ADA4851-2W uses 8-lead MSOP and ADA4851-4W uses 14-lead TSSOP. Pinouts differ across variants-only the single-channel ADA4851-1W variants share identical pin mapping and footprint.
What video standards are explicitly validated for ADA4851-1WYRJZ-R7?
The ADA4851-1WYRJZ-R7 datasheet specifies differential gain (0.08%) and differential phase (0.09°) performance under NTSC conditions at G = +2, RL = 150 Ω, and VOUT = 2 V p-p-directly validating suitability for analog composite video paths in automotive rear-seat entertainment and backup camera systems.
