Product details
Overview
AD8141ACPZ-RL from Analog Devices is a triple, low-cost, differential or single-ended-to-differential video driver IC optimized for RGB signal distribution in high-resolution analog video systems. It delivers 255 MHz large-signal bandwidth, 65 MHz 0.1 dB flatness, 1150 V/μs slew rate, and −50 dB output balance error at 50 MHz-enabling reliable transmission of 1080p/60Hz video over UTP cables such as Cat-5.
For engineers reviewing the AD8141ACPZ-RL datasheet, AD8141ACPZ-RL pinout, AD8141ACPZ-RL application, or AD8141ACPZ-RL equivalent, this page provides verified technical context, real-world interface constraints, supply and termination requirements, and validated alternative options for KVM, digital signage, and security camera video routing designs.
Technical Context
The AD8141ACPZ-RL implements dual-loop feedback: one loop controls differential output voltage (fixed gain = 2), while a separate internal common-mode feedback loop forces each amplifier's output common-mode voltage to match its dedicated VOCM input (VOCMA/VOCMB/VOCMC). This architecture eliminates external balancing components and achieves −50 dB balance error up to 50 MHz without trimming.
Each of the three independent amplifiers supports single 5 V or split ±2.5 V operation, features high-Z disable (DIS pin), delivers 12 ns settling time to 0.1%, and maintains −100 dB inter-amplifier isolation at 10 MHz-critical for crosstalk-sensitive RGB channel separation in broadcast-grade video distribution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Large-signal BW (−3 dB) | 255 MHz - supports full-bandwidth transmission of 1080p/60Hz video signals with minimal amplitude roll-off. |
| 0.1 dB flatness | 65 MHz - ensures color fidelity and edge integrity across HD video bandwidth without equalization. |
| Slew rate | 1150 V/μs - enables clean transient response for fast video sync edges and sharp pixel transitions. |
| Output balance error | −50 dB at 50 MHz - suppresses even-order harmonics and minimizes EMI radiation from differential pairs. |
| Supply current (quiescent) | 44 mA at 5 V - enables low-power operation in multi-channel video encoders and compact KVM switchers. |
| Disable deassert time | 50 ns - allows rapid channel switching in multiplexed video distribution systems with minimal glitching. |
| Operating temperature | −40°C to +85°C - qualified for industrial and outdoor security camera head-end equipment. |
Pinout & Package
AD8141ACPZ-RL is housed in a 24-lead, 4 mm × 4 mm LFCSP package with exposed paddle (EPAD) that must be soldered to ground for thermal and electrical performance. The package supports high-density PCB layouts in space-constrained video interface modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DIS) | Enable/disable control | Asserting low disables all three drivers, placing outputs in high-Z state for multiplexing or power gating. |
| 2, 5, 14, 21 (VS−/GND) | Negative supply / ground reference | Supports single 5 V (GND) or split ±2.5 V operation; multiple pins reduce ground impedance and improve PSRR. |
| 3, 4, 22, 23 (−IN A/+IN A, etc.) | Differential input terminals | Accepts balanced or single-ended inputs; input resistance = 2 kΩ differential, 1.5 kΩ single-ended. |
| 6, 7, 9, 10, 12, 13 (−OUT A/+OUT A, etc.) | Differential output terminals | Drive 200 Ω differential loads; output swing = 0.18 V to 4.6 V (5 V supply); fixed gain = 2. |
| 8, 11, 17, 24 (VS+) | Positive supply | 4.5 V to 5.5 V operation; four pins minimize supply rail inductance and improve transient response. |
| 15, 16, 18, 19, 20 (VOCMC, VOCMB, VOCMA) | Common-mode voltage control | Each VOCM pin sets the DC level of its corresponding amplifier's output common-mode voltage (e.g., VOCMA → Amp A). |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent differential drivers | Enables simultaneous RGB signal conditioning on a single die-reducing component count and board area vs. discrete op-amp solutions. |
| Internal common-mode feedback | Eliminates need for external resistive dividers or trim pots to set output common-mode level; VOCM pins accept 0.2 V to 4.8 V. |
| High inter-amplifier isolation | −100 dB at 10 MHz prevents crosstalk between R/G/B channels-preserving color purity in high-fidelity video routing. |
| Fast disable with low leakage | Outputs go high-Z in 5 ns; disabled output impedance = 11 kΩ at 1 MHz-enables clean analog multiplexing without loading downstream stages. |
| CMOS process with low power | 44 mA quiescent current at 5 V enables thermally constrained designs (e.g., fanless KVM enclosures) without sacrificing speed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple differential driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8142ACPZ-RL | Includes integrated sync-on-common-mode circuitry (HSYNC/VSYNC inputs); no user-accessible VOCM pins; different pinout (SYNC LEVEL, HSYNC, VSYNC instead of VOCMA/B/C). | Designed for embedded sync transmission in RGB+sync systems; not pin-compatible; requires redesign of VOCM control network. | Select AD8142ACPZ-RL only when transmitting horizontal/vertical sync over common-mode channels is required; otherwise AD8141ACPZ-RL offers greater VOCM flexibility. |
| THS7374IPWPR | Triple 6 dB fixed-gain video amplifier; 100 MHz bandwidth; no differential outputs; single-ended I/O; no disable function; SOIC-16 package. | Targeted at legacy CVBS/S-video distribution; lacks differential signaling, common-mode control, and high-speed capability for RGB over UTP. | Choose THS7374IPWPR only for cost-sensitive SD video systems without EMI or long-cable requirements; not suitable for HD RGB distribution. |
Compared with AD8142ACPZ-RL, AD8141ACPZ-RL provides user-configurable VOCM control and pin compatibility for RGB-only systems; compared with THS7374IPWPR, it delivers true differential signaling, 2.5× higher bandwidth, and active disable-making it the only option for noise-immune, long-distance HD video routing.

FAQ
What is the maximum differential load impedance supported by AD8141ACPZ-RL?
AD8141ACPZ-RL is characterized for 200 Ω differential loads (100 Ω per side), which matches standard video termination. While it can drive higher impedances, output swing and settling behavior degrade above 200 Ω due to reduced feedback loop stability and increased sensitivity to PCB parasitics. For optimal 0.1 dB flatness and 12 ns settling, maintain RL,dm = 200 Ω as specified in the datasheet.
Can AD8141ACPZ-RL operate from a single 3.3 V supply?
No. AD8141ACPZ-RL requires a minimum positive supply of 4.5 V and maximum of 5.5 V per Absolute Maximum Ratings (Table 2). Operation at 3.3 V falls outside specification and results in degraded output swing (insufficient headroom for 2× gain), reduced bandwidth, and potential failure to meet 0.1 dB flatness or settling time targets. Use only 4.5 V–5.5 V supplies.
How does the VOCM pin affect output common-mode voltage accuracy?
The VOCM pin directly sets the output common-mode voltage via internal feedback; typical DC gain is 0.98–1.02 V/V, and DC CMRR is −60 dB. At 50 MHz, output balance error remains −50 dB, confirming VOCM tracking holds across video bandwidth. Deviations >±26 mV offset or >±30 µV/°C drift are specified but do not impact functional operation within datasheet limits.
Is AD8141ACPZ-RL pin-compatible with AD8142ACPZ-RL?
No. AD8141ACPZ-RL and AD8142ACPZ-RL have fundamentally different pinouts: AD8141 exposes VOCMA/VOCMB/VOCMC pins (18/19/20) for user-controlled common-mode level, while AD8142 replaces those with HSYNC, VSYNC, and SYNC LEVEL inputs (19/20/18). Pin 1 (DIS) and power pins align, but signal routing is incompatible without PCB redesign.
What is the purpose of the exposed paddle (EPAD) on AD8141ACPZ-RL?
The EPAD on AD8141ACPZ-RL must be soldered to a PCB ground plane to achieve specified thermal resistance (θJA = 38°C/W) and ensure stable operation. Leaving it floating causes junction temperature rise, parametric shift (e.g., reduced bandwidth, increased offset), and potential reliability failure. Thermal performance degrades by >20°C/W if EPAD is unconnected.
