Product details
Overview
AD8133ACPZ-REEL7 from Analog Devices is a triple, high-speed, fully differential driver IC with output pull-down capability, fixed gain of 2, 225 MHz large-signal bandwidth, 1600 V/µs slew rate, and −60 dB output balance error at 50 MHz. It drives RGB video signals over Category 5 UTP cable in KVM systems with line isolation via OPD control.
For engineers reviewing the AD8133ACPZ-REEL7 datasheet, AD8133ACPZ-REEL7 pinout, AD8133ACPZ-REEL7 application, or AD8133ACPZ-REEL7 equivalent, key selection criteria include differential-to-differential conversion performance, VOCM-adjustable common-mode level, output pull-down timing (100 ns assert/de-assert), and thermal management of the 24-lead LFCSP package.
Technical Context
The AD8133ACPZ-REEL7 integrates three independent differential drivers, each with dual feedback loops: one for differential gain control (fixed 2×) and one for common-mode voltage regulation via VOCMA/VOCMB/VOCMC pins. This architecture enables precise output amplitude/phase matching without external trimming.
Each amplifier supports single-ended-to-differential or differential-to-differential operation, features internal 1.5 kΩ differential input resistance, and delivers balanced outputs with <±24 mV output offset and 25 nV/√Hz output-referred noise at 1 MHz. The OPD pin provides fast (100 ns), low-voltage output state control for multiplexed UTP line isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Large-signal bandwidth | 225 MHz at 2 Vp-p output - supports full HD RGB video transmission over UTP. |
| Slew rate | 1600 V/µs - ensures minimal distortion on fast edge transitions in high-resolution video signals. |
| Output balance error | −60 dB at 50 MHz - suppresses even-order harmonics and EMI in differential signaling paths. |
| Fixed differential gain | 1.925–2.000 V/V - compensates for 2× attenuation of 100 Ω source-terminated UTP lines. |
| OPD assert/de-assert time | 100 ns - enables rapid channel switching in KVM matrix applications without signal glitches. |
| Quiescent current | 26 mA at +5 V supply - enables low-power operation across all three drivers simultaneously. |
| Operating temperature | −40°C to +85°C - qualified for industrial-grade embedded video infrastructure deployment. |
Pinout & Package
The AD8133ACPZ-REEL7 is housed in a 24-lead, 4 mm × 4 mm LFCSP package with exposed paddle (EPAD) requiring soldering to a thermally vias-connected PCB plane for θJA = 70°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OPD) | Output Pull-Down control | Asserts low-voltage state (<0.9 V above VS−) on all six outputs for line isolation in multiplexed UTP systems. |
| 2,5,14,21 (VS−) | Negative power supply | Accepts single +5 V or dual ±5 V supplies; shared return for all three amplifiers. |
| 3,23 (−IN A/B/C) | Inverting inputs | Differential input pairs per channel; 1.5 kΩ differential input impedance minimizes loading. |
| 4,22 (+IN A/B/C) | Noninverting inputs | Supports single-ended input when opposite input is biased; enables flexible signal routing. |
| 6,10,13 (−OUT A/B/C) | Negative differential outputs | Complement outputs referenced to VOCM; matched to +OUT pins for <−60 dB balance error. |
| 7,9,12 (+OUT A/B/C) | Positive differential outputs | Drive 100 Ω UTP loads directly; swing to VS+ − 1.6 V / VS− + 1.9 V under ±5 V supply. |
| 8,11,17,24 (VS+) | Positive power supply | Four dedicated VS+ pins reduce supply impedance and improve PSRR (−84 dB). |
| 15,16 (+IN C / −IN C) | Channel C inputs | Identical electrical specs to Channels A/B; fully independent operation with no crosstalk degradation. |
| 18,19,20 (VOCMC/B/A) | Output common-mode control | Set individual output DC level from 1.25 V to 3.85 V (single-supply) or ±3.1 V (dual-supply); 0.98–1.005 V/V tracking gain. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent differential drivers | Enables simultaneous RGB signal transmission without inter-channel skew or crosstalk (81 dB isolation @ 10 MHz). |
| Internal common-mode feedback loop | Maintains output balance <−60 dB up to 50 MHz, eliminating need for external matching components. |
| Adjustable VOCM per channel | Allows independent DC level setting for each differential pair-critical for multi-voltage-domain video interfaces. |
| Output pull-down (OPD) with 100 ns timing | Permits hardware-controlled line disconnection in KVM switchers without external MOSFETs or logic. |
| 24-lead LFCSP with EPAD | 4 mm × 4 mm footprint saves board space; exposed paddle enables thermal dissipation up to 3.5 W at 25°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8132ARZ | Dual-channel (not triple); identical bandwidth, gain, and VOCM architecture but lacks third driver and OPD pin. | Suitable only for dual-signal applications (e.g., Y/C or stereo audio); cannot replace AD8133ACPZ-REEL7 in RGB systems without redesign. | Select AD8132ARZ only when driving two differential signals and board space/power budget constrain triple-channel use. |
| THS4521DR | Single-channel, 3.5 GHz small-signal BW, rail-to-rail output, no integrated OPD or VOCM pin-requires external feedback network for gain/CM control. | Better suited for RF/data-acquisition where ultra-wide bandwidth outweighs integration; not drop-in for UTP video due to missing OPD and triple-channel capability. | Choose THS4521DR for high-frequency instrumentation where flexibility > integration; avoid for RGB/UTP KVM without added support circuitry. |
Compared with AD8132ARZ and THS4521DR, the AD8133ACPZ-REEL7 uniquely combines triple-channel operation, integrated OPD for hardware-multiplexed UTP, and per-channel VOCM control-making it irreplaceable in compact, low-component-count RGB-over-UTP designs.

FAQ
What is the function of the OPD pin on the AD8133ACPZ-REEL7?
The OPD (Output Pull-Down) pin on the AD8133ACPZ-REEL7 enables hardware-controlled line isolation: when asserted high, it pulls all six differential outputs to within 0.9 V above VS− in ≤100 ns. This feature eliminates signal leakage during channel switching in KVM or video multiplexer designs, and is integral to the AD8133ACPZ-REEL7's architecture-no external components required.
Can the AD8133ACPZ-REEL7 operate from a single +5 V supply?
Yes, the AD8133ACPZ-REEL7 supports single +5 V operation with VOCM inputs biased between 1.25 V and 3.85 V. Under this condition, it delivers 200 MHz large-signal bandwidth, 1400 V/µs slew rate, and ±1.15 V single-ended output swing relative to VS−. All specifications-including OPD behavior and output balance-are validated across the full −40°C to +85°C range on +5 V supply.
How does the VOCM pin affect differential output performance in the AD8133ACPZ-REEL7?
The VOCM pins (VOCMA/VOCMB/VOCMC) on the AD8133ACPZ-REEL7 set the DC common-mode voltage of each differential pair independently, with 0.98–1.005 V/V tracking gain and 290–330 MHz bandwidth. This control does not affect differential gain or balance-output differential swing remains fixed at 2× input, while common-mode level shifts precisely per VOCM voltage, enabling level translation between disparate video subsystems.
What is the thermal design requirement for the AD8133ACPZ-REEL7 LFCSP package?
The AD8133ACPZ-REEL7 uses a 24-lead LFCSP with exposed paddle (EPAD) that must be soldered to a PCB copper plane connected via ≥4 thermal vias to inner ground/power layers. This achieves θJA = 70°C/W on a 4-layer board. Without proper EPAD connection, junction temperature may exceed 150°C at 26 mA quiescent current, risking parametric shift or reliability degradation.
Is the AD8133ACPZ-REEL7 pin-compatible with other members of the AD813x family?
No-the AD8133ACPZ-REEL7 has a unique 24-pin LFCSP layout with dedicated VOCMA/VOCMB/VOCMC and OPD pins not present in AD8132 (dual-channel, 16-pin SOIC) or AD8130 (single-channel, 8-pin SOIC). Pin mapping, supply pin count (four VS+), and thermal pad configuration differ fundamentally; PCB layout is not interchangeable across the AD813x family.
