Product details
Overview
ADA4851-2YRMZ-RL7 from Analog Devices is a dual, rail-to-rail output, voltage-feedback operational amplifier optimized for high-speed video and general-purpose signal conditioning. It delivers 130 MHz −3 dB bandwidth (G = +1), 375 V/μs slew rate (±5 V supply), 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 make it suitable for NTSC video reconstruction in automotive infotainment systems.
For engineers reviewing the ADA4851-2YRMZ-RL7 datasheet, ADA4851-2YRMZ-RL7 pinout, ADA4851-2YRMZ-RL7 application, or ADA4851-2YRMZ-RL7 equivalent, key selection criteria include its dual-channel MSOP-8 package, rail-to-rail output swing within 60 mV of either rail, low 2.5 mA per amplifier quiescent current, and guaranteed −40°C to +125°C operation for automotive-grade designs.
Technical Context
The ADA4851-2YRMZ-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 (≤70 ns rise, ≤100 ns fall under overdrive). 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 operation.
It features matched dual amplifiers on a monolithic die with crosstalk of −70 dB (RTI, 5 MHz), ensuring channel independence in multi-path video routing and active filter applications. The device is not power-down capable-only the single-channel ADA4851-1 includes that function.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 130 MHz at G = +1, ±5 V supply - supports high-definition video baseband signal amplification without attenuation |
| Slew Rate | 375 V/μs at G = +2, ±5 V - enables clean reproduction of fast transient video edges and clock signals |
| Settling Time | 55 ns to 0.1% at G = +2, RL = 150 Ω - meets timing requirements for SD/HD video switching and reconstruction filters |
| Differential Gain / Phase | 0.08% / 0.09° at NTSC, RL = 150 Ω - preserves color fidelity in consumer and automotive video signal paths |
| Rail-to-Rail Output Swing | Within 60 mV of either supply rail - maximizes dynamic range in low-voltage (e.g., +3.3 V or +5 V) systems |
| Quiescent Current | 2.5 mA per amplifier - balances speed and power efficiency for battery-sensitive or thermally constrained designs |
| Supply Range | 2.7 V to 12 V single supply or ±5 V dual supply - supports wide-range industrial and automotive power architectures |
Pinout & Package
ADA4851-2YRMZ-RL7 is housed in an 8-lead MSOP (RM-8) package with exposed pad for thermal enhancement. Pin 1 is marked by a dot or beveled edge; the package is RoHS-compliant and moisture-sensitive level 1 (MSL 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 (+IN1) | Non-inverting input, Amp 1 | High-impedance node (5 MΩ common-mode); accepts sensor, DAC, or video source inputs |
| 4 (–VS) | Negative supply rail | Reference for dual-supply operation; tied to ground in single-supply mode |
| 5 (+IN2) | Non-inverting input, Amp 2 | Independent input path; enables dual-channel signal processing without cross-coupling |
| 6 (–IN2) | Inverting input, Amp 2 | Separate feedback node; allows independent gain setting per channel |
| 7 (OUT2) | Amplifier 2 output | Second rail-to-rail output; supports stereo video, dual ADC drivers, or redundant signal paths |
| 8 (+VS) | Positive supply rail | Supports up to +12 V or +5 V; powers both amplifiers simultaneously |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings to within 60 mV of either supply rail across full temperature range (−40°C to +125°C), preserving signal headroom in low-voltage systems |
| Automotive qualification | Specified and tested over −40°C to +125°C; qualified per AEC-Q100 (implied by ADA4851-2W designation and "automotive grade" labeling in datasheet) |
| Video-optimized distortion performance | 0.08% differential gain and 0.09° differential phase at NTSC ensure minimal color shift in analog video signal chains |
| Low input offset voltage | 0.6 mV typical (max 3.4 mV at +5 V) - reduces DC error in precision gain stages and sensor interfaces |
| Wide supply flexibility | Operates from 2.7 V single supply to ±5 V dual supply - simplifies integration into mixed-voltage automotive ECUs and industrial controllers |

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 |
|---|---|---|---|
| ADA4851-2ARZ-RL7 | Same silicon, but in 8-lead SOIC_N (N-8) package; larger footprint, higher θJA (130°C/W vs. 150°C/W for MSOP) | Better suited for prototyping or boards with relaxed space constraints; less optimal for dense automotive PCBs | Select ADA4851-2ARZ-RL7 when SOIC layout compatibility or hand-soldering is required; ADA4851-2YRMZ-RL7 preferred for space-constrained automotive modules. |
| LMH6629MA/NOPB | Higher bandwidth (1.5 GHz), higher quiescent current (12.5 mA), no guaranteed automotive temp range; not AEC-Q100 qualified | Targeted at test equipment and high-frequency instrumentation, not automotive or video broadcast | Choose LMH6629MA/NOPB only for >500 MHz small-signal applications where power and temperature range are secondary. |
Compared with ADA4851-2ARZ-RL7, ADA4851-2YRMZ-RL7 offers 35% smaller PCB area and improved thermal resistance for automotive under-hood environments; compared with LMH6629MA/NOPB, it trades bandwidth for lower power, guaranteed automotive qualification, and video-optimized linearity.

FAQ
What is the operating temperature range for ADA4851-2YRMZ-RL7?
The ADA4851-2YRMZ-RL7 is specified and tested over −40°C to +125°C, meeting automotive-grade requirements. This range is explicitly confirmed in the General Description section and Absolute Maximum Ratings table of the Rev. J datasheet, and applies to all variants including the YRMZ-RL7 MSOP-8 packaging.
Does ADA4851-2YRMZ-RL7 support power-down functionality?
No, ADA4851-2YRMZ-RL7 does not include a power-down feature. Power-down capability is exclusive to the single-channel ADA4851-1 variant (e.g., ADA4851-1ARMZ-RL7), as documented in Tables 1–3 under "POWER-DOWN-ADA4851-1 ONLY". The dual-channel ADA4851-2 has no dedicated power-down pin or internal circuitry for standby mode.
What is the maximum load capacitance ADA4851-2YRMZ-RL7 can drive stably?
ADA4851-2YRMZ-RL7 maintains stability driving up to 10 pF capacitive load with 1 kΩ series resistance (Figure 9 in Rev. J datasheet). For direct capacitive loads >5 pF, a 10–50 Ω series resistor at the output is recommended to prevent peaking or oscillation, especially at gains ≥+2 and frequencies above 10 MHz.
Is ADA4851-2YRMZ-RL7 pin-compatible with other members of the ADA4851 family?
ADA4851-2YRMZ-RL7 (MSOP-8) shares identical pinout with ADA4851-2ARZ-RL7 (SOIC-8) and ADA4851-2WYRMZ-RL7 (automotive-grade MSOP-8), as shown in Figure 2 of the Rev. J datasheet. However, it is not pin-compatible with the single-channel ADA4851-1 or quad ADA4851-4 due to differing pin counts and functions.
What video standards does ADA4851-2YRMZ-RL7 support with guaranteed performance?
ADA4851-2YRMZ-RL7 guarantees 0.08% differential gain and 0.09° differential phase for NTSC video signals (as measured in Table 2 and Table 3), and provides 0.1 dB flatness to 11 MHz - sufficient for NTSC, PAL, and standard-definition component video (Y/Pb/Pr) applications. Performance for HD formats (e.g., 720p/1080i) is supported via its 130 MHz bandwidth but not explicitly characterized in the datasheet for those standards.
