Product details
Overview
AD8133ACPZ-REEL from Analog Devices is a triple high-speed fully differential driver IC designed for RGB video signal conditioning and UTP cable driving in KVM systems. It delivers 225 MHz large-signal bandwidth, 1600 V/µs slew rate, fixed gain of 2, and output pull-down capability for line isolation-enabling differential multiplexing over shared twisted-pair infrastructure.
For engineers reviewing the AD8133ACPZ-REEL datasheet, AD8133ACPZ-REEL pinout, AD8133ACPZ-REEL application, or AD8133ACPZ-REEL equivalent, key selection criteria include differential output balance (−60 dB @ 50 MHz), adjustable VOCM control, ±5 V / +5 V supply flexibility, and 24-lead LFCSP thermal performance with exposed paddle.
Technical Context
The AD8133ACPZ-REEL integrates three independent differential drivers, each with dual feedback loops: one for differential-mode gain (fixed 2× via internal 1.5 kΩ/750 Ω resistor ratio) and one for common-mode control via dedicated VOCM pins (VOCMA/VOCMB/VOCMC). This architecture enables precise, frequency-stable output balance without external trimming.
Each amplifier supports single-ended-to-differential or differential-to-differential operation, with input common-mode range spanning −5 V to +5 V (±5 V supply) or 0–5 V (+5 V supply), and features an OPD pin that asserts sub-1 V output pull-down relative to VS− within 100 ns for active line isolation in multiplexed video routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Large-signal BW | 225 MHz @ 2 Vp-p - supports full-bandwidth RGB video transmission over Category 5 UTP. |
| Slew rate | 1600 V/µs - ensures minimal distortion on fast video edges and sync pulses. |
| Output balance error | −60 dB @ 50 MHz - suppresses even-order harmonics and EMI in differential signaling. |
| Differential gain | 1.925–2.000 V/V - compensates for 2× attenuation in source-terminated 100 Ω differential lines. |
| OPD assert time | 100 ns - enables rapid channel switching in KVM matrix applications without visible glitching. |
| Quiescent current | 26 mA @ +5 V - low power for triple-driver operation in space-constrained embedded video systems. |
| Supply range | +4.5 V to ±6 V - supports both single-supply (5 V) and bipolar (±5 V) operation in legacy and new designs. |
Pinout & Package
The AD8133ACPZ-REEL is housed in a 24-lead 4 mm × 4 mm LFCSP package with exposed thermal paddle (EPAD) requiring solder connection to PCB ground plane for thermal management (θJA = 70°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OPD) | Output Pull-Down Enable | Asserting high disables outputs and pulls all six single-ended outputs to VS− + 0.79–0.90 V for diode-based line isolation. |
| 2,5,14,21 (VS−) | Negative Supply Rail | Common return for all three amplifiers; must be decoupled with 0.1 µF ceramic capacitors. |
| 3,23 (−IN A/B/C) | Inverting Input per Channel | Differential input pair per amplifier; matched impedance (1.5 kΩ diff) minimizes imbalance-induced distortion. |
| 4,22 (+IN A/B/C) | Noninverting Input per Channel | Accepts single-ended or differential inputs; input common-mode range adapts to supply configuration. |
| 6,10,13 (−OUT A/B/C) | Negative Output per Channel | One leg of true differential output; balanced against corresponding +OUT pin with <−60 dB error @ 50 MHz. |
| 7,9,12 (+OUT A/B/C) | Positive Output per Channel | Complementary output leg; combined with −OUT forms 200 Ω differential load interface. |
| 8,11,17,24 (VS+) | Positive Supply Rail | Shared rail for all amplifiers; requires local 0.1 µF decoupling at each pin per test circuit. |
| 18,19,20 (VOCMC/B/A) | Per-Channel VOCM Control | Set output common-mode voltage independently per driver; DC gain = 0.98–1.005 V/V, BW = 290–330 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent drivers | Three fully isolated differential amplifiers in one 4 mm × 4 mm LFCSP-reduces board area vs. discrete op-amp solutions. |
| Internal common-mode feedback | Enables VOCM-controlled output level shifting without affecting differential gain or phase matching. |
| Output balance optimization | −60 dB balance error at 50 MHz ensures minimal radiated EMI and harmonic distortion in high-speed video links. |
| Adjustable VOCM bandwidth | 330 MHz (±5 V) / 290 MHz (+5 V) VOCM path allows high-fidelity common-mode signal overlay (e.g., sync-on-common-mode). |
| Low-distortion driving | 64 dB SFDR @ 10 MHz into 200 Ω load-meets broadcast-grade video fidelity requirements. |
Applications
| KVM Switching Matrix | UTP-Based RGB Video Distribution |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple differential driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8132ARMZ | Dual-channel (not triple); identical gain, bandwidth, and VOCM architecture; 8-lead MSOP package. | Lacks third channel; suitable only when two differential outputs suffice (e.g., Y/C or stereo audio). | Select AD8132ARMZ only if system requires exactly two drivers and board space favors MSOP over LFCSP. |
| THS4521IRGTR | Single-channel; higher 3-GHz GBW but no integrated OPD; requires external VOCM buffer; 16-pin QFN. | No native line-isolation capability; VOCM drive strength limited; needs additional components for triple-channel use. | Choose THS4521IRGTR only for ultra-high-frequency (>500 MHz) single-channel applications where OPD is unnecessary. |
Compared with AD8133ACPZ-REEL, AD8132ARMZ saves board area but halves channel count, while THS4521IRGTR offers wider bandwidth at the cost of integration and multiplexing readiness-making AD8133ACPZ-REEL uniquely suited for compact, multi-channel UTP video routing.

FAQ
What is the operating temperature range for the AD8133ACPZ-REEL?
The AD8133ACPZ-REEL is rated for continuous operation from −40°C to +85°C ambient temperature. This industrial-grade range is validated across all electrical specifications in the datasheet, including gain flatness, output balance, and OPD timing, making it suitable for deployment in embedded KVM hardware and outdoor AV enclosures without derating.
Does the AD8133ACPZ-REEL support single-ended input configurations?
Yes, the AD8133ACPZ-REEL supports both differential and single-ended input modes. When driven single-ended (e.g., grounding one input), its input impedance is 1.13 kΩ per leg, and the internal feedback network maintains 2× differential gain. The input common-mode voltage range adjusts automatically: −5 V to +5 V under ±5 V supply, or 0–5 V under +5 V supply.
How does the VOCM pin function in the AD8133ACPZ-REEL?
Each AD8133ACPZ-REEL channel has a dedicated VOCM pin (VOCMA/VOCMB/VOCMC) that directly sets the output common-mode voltage with 0.98–1.005 V/V DC gain and 290–330 MHz bandwidth. Applying 2.5 V to VOCMA forces both +OUT A and −OUT A to center at 2.5 V, regardless of differential swing-enabling level-shifting to match downstream receivers like AD8129 or AD8130.
What is the purpose of the OPD pin on the AD8133ACPZ-REEL?
The OPD (Output Pull-Down) pin on the AD8133ACPZ-REEL provides hardware-controlled line isolation: asserting OPD high pulls all six single-ended outputs to VS− + 0.79–0.90 V within 100 ns. This enables clean channel switching in multiplexed UTP systems when used with series diodes, eliminating crosstalk and display artifacts during source transitions.
Can the AD8133ACPZ-REEL drive 100 Ω differential loads directly?
Yes, the AD8133ACPZ-REEL is explicitly characterized driving 200 Ω differential loads (RL,dm = 200 Ω), which corresponds to two 100 Ω terminations-one at each end of a UTP cable. Its output stage delivers 90 mA short-circuit current and maintains −60 dB balance error and 225 MHz bandwidth into this load, meeting Category 5 UTP video transmission requirements without external buffering.
