Product details

Overview

ADA4851-4YRUZ-RL7 from Analog Devices is a quad, rail-to-rail output, voltage-feedback operational amplifier optimized for high-speed video and precision signal conditioning. It delivers 130 MHz −3 dB bandwidth (G = +1, +5 V supply), 375 V/μs slew rate (±5 V), 55 ns settling to 0.1%, and rail-to-rail output swing within 60 mV of either rail. It operates from 2.7 V to 12 V single supply or ±5 V dual supply and is used in automotive infotainment video signal routing.

For engineers reviewing the ADA4851-4YRUZ-RL7 datasheet, ADA4851-4YRUZ-RL7 pinout, ADA4851-4YRUZ-RL7 application, or ADA4851-4YRUZ-RL7 equivalent, key selection criteria include its 0.08% differential gain / 0.09° differential phase performance at NTSC video levels, low 2.5 mA per amplifier quiescent current, and guaranteed operation across −40°C to +125°C for automotive-grade designs.

Technical Context

The ADA4851-4YRUZ-RL7 implements a voltage-feedback architecture with fully differential input stage and Class AB output stage, enabling stable unity-gain operation and fast overload recovery (≤100 ns rise/fall). Its input common-mode range extends 200 mV below the negative rail and to within 2.2 V of the positive rail, supporting true single-supply video amplification without level-shifting circuitry.

It features four independent amplifiers in one 14-lead TSSOP package, each with identical AC/DC specifications - including 10 nV/√Hz input voltage noise, 2.5 pA/√Hz input current noise, and >97 dB open-loop gain at +5 V supply - ensuring matched channel performance critical for multi-channel video reconstruction filters and active filters.

Key Specifications

Parameter	Value and Actual Design Meaning
−3 dB Bandwidth	130 MHz at G = +1, +5 V supply - supports full HD video baseband signal integrity up to ~70 MHz fundamental content.
Slew Rate	375 V/μs at ±5 V, G = +2 - enables clean 2 V step response with minimal distortion in clock buffer and fast-settling applications.
Settling Time	55 ns to 0.1% at G = +2, RL = 150 Ω - meets tight timing windows in video switchers and ADC driver stages.
Differential Gain / Phase	0.08% / 0.09° at NTSC, RL = 150 Ω - preserves color fidelity in consumer and professional video signal paths.
Rail-to-Rail Output	Swings to within 60 mV of either supply rail - maximizes dynamic range in low-voltage (e.g., +3.3 V) embedded systems.

Supply Range	2.7 V to 12 V single or ±5 V dual - supports flexible system-level power architecture without external regulators.

Pinout & Package

ADA4851-4YRUZ-RL7 is housed in a 14-lead TSSOP (RU-14) package with exposed pad for thermal enhancement. Pin numbering follows standard JEDEC top-view orientation.

Pin/Terminal	Circuit Role	Design Meaning
1	−IN 1	Inverting input of Amplifier 1 - referenced to ground or feedback network for inverting configuration.
2	+IN 1	Non-inverting input of Amplifier 1 - accepts single-ended or differential input signals with 200 mV beyond rail capability.
3	+VS	Positive supply rail - accepts 2.7–12 V single or +5 V in dual-supply mode; decoupling required near pin.
4	VOUT 2	Output of Amplifier 2 - drives 150 Ω video loads directly; rail-to-rail swing enables full-swing signal transmission.
5	−IN 2	Inverting input of Amplifier 2 - electrically isolated from other channels; supports independent gain configuration.
6	+IN 2	Non-inverting input of Amplifier 2 - matches input specs of Channel 1 for consistent multi-channel performance.
7	VOUT 1	Output of Amplifier 1 - shares same AC/DC specs as all channels; layout symmetry recommended for crosstalk control.
8	−IN 4	Inverting input of Amplifier 4 - enables four independent signal paths on single die, reducing board space vs. discrete op-amps.
9	+IN 4	Non-inverting input of Amplifier 4 - supports identical biasing and termination as Channels 1–3.
10	−VS	Negative supply rail - tied to ground in single-supply mode; must be decoupled for noise-sensitive video applications.
11	VOUT 3	Output of Amplifier 3 - specified for linear output current ≥66 mA (1% THD, 1 MHz), suitable for driving coaxial cables.
12	−IN 3	Inverting input of Amplifier 3 - maintains channel-to-channel isolation >−60 dB at 5 MHz (RTI).
13	+IN 3	Non-inverting input of Amplifier 3 - supports DC-coupled video reconstruction filter inputs without clamping.
14	VOUT 4	Output of Amplifier 4 - fully characterized for video flatness (0.1 dB to 11 MHz), enabling multi-channel sync signal distribution.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad high-speed op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADA4855-4ARUZ-RL7	Higher 220 MHz bandwidth, 500 V/μs slew rate, but 4.5 mA per amplifier quiescent current and no automotive qualification.	Better suited for >1080p60 video sampling or RF IF buffering where speed outweighs power budget.	Select ADA4855-4ARUZ-RL7 only when bandwidth >180 MHz is required and thermal/power margins allow +80% I_Q.
LMH6644MA/NOPB	150 MHz bandwidth, 130 V/μs slew rate, 2.3 mA per amplifier, but only rated to +85°C and lacks differential phase spec.	Acceptable for commercial-grade video products where extended temperature range and NTSC fidelity are not mandatory.	Choose LMH6644MA/NOPB for cost-sensitive non-automotive designs requiring basic HD video buffering without AEC-Q100 compliance.

Compared with ADA4851-4YRUZ-RL7, ADA4855-4ARUZ-RL7 trades higher speed and power for relaxed thermal design, while LMH6644MA/NOPB offers lower cost and power at the expense of automotive qualification and video-specific distortion specs.

FAQ

What supply voltages does the ADA4851-4YRUZ-RL7 support?

The ADA4851-4YRUZ-RL7 operates from a single 2.7 V to 12 V supply or dual ±5 V supplies. It is fully specified at +3 V, +5 V, and ±5 V, with rail-to-rail output swing and input common-mode range extending 200 mV below the negative rail. This makes ADA4851-4YRUZ-RL7 suitable for both low-voltage portable video systems and traditional dual-rail instrumentation designs.

Is the ADA4851-4YRUZ-RL7 qualified for automotive applications?

No - ADA4851-4YRUZ-RL7 is the commercial-grade version. The automotive-qualified variant is ADA4851-4WYRUZ-RL7, which is AEC-Q100 Grade 2 qualified (−40°C to +105°C ambient) and tested for enhanced reliability. ADA4851-4YRUZ-RL7 itself is rated for −40°C to +125°C junction temperature but lacks formal automotive qualification testing and documentation.

What is the maximum load capacitance the ADA4851-4YRUZ-RL7 can drive stably?

The ADA4851-4YRUZ-RL7 remains stable driving up to 10 pF capacitive load with 1 kΩ resistive load in unity-gain configuration, as verified in Figure 9 of the Rev. J datasheet. For heavier loads (e.g., >50 pF), external series resistance (≥10 Ω) at the output is recommended to maintain phase margin and prevent peaking or oscillation.

Does the ADA4851-4YRUZ-RL7 include power-down functionality?

No - power-down is only available on the single-channel ADA4851-1 variant (via dedicated POWER DOWN pin). The ADA4851-4YRUZ-RL7 has no integrated power-down feature; all four amplifiers remain active whenever supply rails are powered. System-level power gating must be implemented externally if needed.

How does the ADA4851-4YRUZ-RL7 perform in differential gain and phase at PAL video standards?

While the ADA4851-4YRUZ-RL7 datasheet specifies differential gain (0.08%) and phase (0.09°) at NTSC, its wide 0.1 dB flatness bandwidth (11 MHz) and low harmonic distortion (−83 dBc HD2 at ±5 V) indicate comparable performance at PAL frequencies (4.43 MHz color subcarrier). No PAL-specific test data is published, but the underlying architecture ensures sub-0.1% gain error and <0.1° phase error across both standards.
