Product details
Overview
MAX9584AUA+T from Maxim Integrated is a triple-channel standard-definition video filter amplifier with integrated 8.5MHz reconstruction filters, fixed 2V/V gain, and DC-coupled input buffers. It operates from a 2.7V–3.6V single supply, draws 3.5mA per channel, and drives 75Ω or 150Ω video loads in televisions, set-top boxes, and portable video systems.
For engineers reviewing the MAX9584AUA+T datasheet, MAX9584AUA+T pinout, MAX9584AUA+T application, or MAX9584AUA+T equivalent, this page delivers verified electrical specs, automotive-grade (-40°C to +125°C) performance data, µMAX-8 package details, and real-world video signal conditioning use cases - all confirmed from Maxim's official documentation.
Technical Context
The MAX9584AUA+T integrates three identical channels, each comprising a high-impedance DC-coupled input buffer, an 8.5MHz ±1dB passband lowpass filter, and a 2V/V gain output amplifier capable of sourcing/sinking current for DC- or AC-coupled 75Ω/150Ω loads. Input voltage range is 0V to 1.05V (at VDD = 2.7V), and output sync tip is internally level-shifted to ~300mV.
It features 55dB attenuation at 27MHz, <0.1% differential gain error, <0.4° differential phase error at 4.43MHz, and -64dB all-hostile crosstalk. Designed for composite (CVBS), luma/chroma (Y/C), and RGB video DAC outputs, it supports direct connection without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Triple-channel - simultaneously conditions three independent SD video signals (e.g., Y/C/CVBS or R/G/B). |
| Supply Voltage | 2.7V to 3.6V single supply - enables low-power operation in battery-powered and automotive infotainment systems. |
| Quiescent Current | 3.5mA per channel - reduces total system power by >50% versus discrete op-amp + filter solutions. |
| Filter Passband | 8.5MHz ±1dB - fully supports NTSC (4.2MHz), PAL (5MHz), and oversampled DVD (≤6.75MHz) baseband video bandwidths. |
| Differential Gain/Phase | 0.1% / 0.4° at 4.43MHz - preserves color fidelity in composite video without requiring external calibration. |
| Output Drive | DC-coupled to 75Ω (two loads at VDD ≥ 3.135V) or AC-coupled to 150Ω - eliminates coupling capacitors in some designs and simplifies layout. |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive video displays and industrial set-top box applications. |
Pinout & Package
The MAX9584AUA+T is housed in an 8-pin µMAX package (3mm × 3mm, 0.6mm height), lead-free and RoHS-compliant. Pin spacing is 0.5mm, with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INA | Video Input A | DC-coupled high-impedance input for first SD video signal (e.g., luma, R, or CVBS). |
| 2 INB | Video Input B | DC-coupled high-impedance input for second SD video signal (e.g., chroma, G, or auxiliary CVBS). |
| 3 INC | Video Input C | DC-coupled high-impedance input for third SD video signal (e.g., B, Y, or secondary CVBS). |
| 4 GND | Ground | Analog ground reference for all inputs, filters, and outputs; must be low-impedance and star-connected. |
| 5 OUTC | Video Output C | Filtered, 2V/V-gain amplified output for third channel; capable of driving 75Ω DC-coupled or 150Ω AC-coupled loads. |
| 6 OUTB | Video Output B | Filtered, 2V/V-gain amplified output for second channel; matches OUTC in drive strength and level-shifting. |
| 7 OUTA | Video Output A | Filtered, 2V/V-gain amplified output for first channel; sync tip positioned at ~300mV, blank level scaled per input. |
| 8 VDD | Positive Supply | 2.7V–3.6V analog supply; requires local 0.1µF ceramic bypass capacitor to GND for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 8.5MHz Reconstruction Filter | Eliminates need for external RC/LC filters while maintaining ±1dB flatness and 55dB stopband attenuation at 27MHz. |
| DC-Coupled Input Buffers | Accepts ground-referenced video DAC outputs (0–1.05V) without external biasing or level-shifting circuitry. |
| Internal Sync Tip Level-Shift | Positions output sync tip at ~300mV automatically - removes requirement for external clamping diodes or DC restorers. |
| Low Crosstalk (-64dB) | Prevents interference between channels in multi-signal routing (e.g., RGB or YPbPr), preserving signal integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-channel SD video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9584AUA+ | Same die, same µMAX-8 package, but supplied in cut tape (no 'T' suffix); identical electrical specs and pinout. | No functional difference - differs only in packaging format (tape-and-reel vs. cut tape) and reel quantity. | Select MAX9584AUA+T for automated SMT assembly; MAX9584AUA+ for prototyping or low-volume hand soldering. |
| LMH6739MA/NOPB | Single-channel, wideband op-amp (200MHz GBW); no integrated filter, no DC-coupled input buffer, no sync-tip level shift. | Requires external 8.5MHz filter, input biasing, and output clamping - increases BOM count and layout complexity. | Choose only if full-bandwidth flexibility (>27MHz) is required and system-level filtering can be implemented externally. |
Compared with MAX9584AUA+T, the MAX9584AUA+ offers identical performance in cut-tape form, while the LMH6739MA/NOPB demands significant external circuitry to match basic SD video conditioning - making MAX9584AUA+T the optimal choice for cost-sensitive, space-constrained, and production-ready SD video designs.

FAQ
What is the maximum input voltage range supported by the MAX9584AUA+T?
The MAX9584AUA+T supports an input voltage range of 0V to 1.05V when VDD = 2.7V, and 0V to 1.2V when VDD = 3V. This range accommodates standard-definition video DAC outputs including sync tip (0–50mV), blank level (0.5–0.65V for chroma), and active video (up to 1.05V), ensuring compatibility with NTSC, PAL, and RGB sources without external level shifting.
Can the MAX9584AUA+T drive two 75Ω loads simultaneously?
Yes - the MAX9584AUA+T can drive two DC-coupled 75Ω loads (i.e., 37.5Ω total) when VDD ≥ 3.135V (5% below 3.3V). At lower supply voltages (e.g., 2.7V–3.135V), it supports only one 75Ω DC-coupled load or one 150Ω AC-coupled load per channel. This capability simplifies dual-output designs such as mirrored CVBS feeds in STBs.
Does the MAX9584AUA+T require external passive components for basic operation?
The MAX9584AUA+T requires only a 0.1µF ceramic capacitor between VDD and GND for power-supply bypassing. No external resistors, capacitors, or inductors are needed for filter function, gain setting, or DC biasing - all reconstruction filtering, 2V/V gain, and sync-tip level shifting are fully integrated, minimizing bill-of-materials and layout effort.
How does the MAX9584AUA+T handle chroma blank level translation?
The MAX9584AUA+T internally translates chroma blank level: a 0.5V input blank level yields ~1.3V at the output, and a 0.6V input yields ~1.5V. This automatic scaling ensures proper black-level alignment in downstream video processing or display circuits without external resistor dividers or op-amp offsets - critical for consistent color reproduction across temperature.
Is the MAX9584AUA+T pin-compatible with other members of the MAX9583/84/85 family?
No - the MAX9584AUA+T (8-pin µMAX) is not pin-compatible with the MAX9583AZT+T (6-pin SOT23) or MAX9585AUB+T (10-pin µMAX). Each variant has distinct pin counts, layouts, and channel counts. However, all share identical electrical behavior per channel, enabling scalable design reuse across dual/triple/quad configurations when board layout permits re-spin.
