Product details
Overview
The MAX9586AZK+ from Maxim Integrated is a single-channel standard-definition video filter amplifier with integrated reconstruction filter, sync-tip clamp, and 2V/V gain output stage, designed for AC-coupled CVBS/luma signal conditioning in automotive-grade (-40°C to +125°C) set-top boxes and televisions. It operates from a 2.7V–3.6V supply, draws 4.25mA per channel, delivers ±1dB passband flatness to 8.5MHz, and provides 55dB attenuation at 27MHz.
For engineers reviewing the MAX9586AZK+ datasheet, MAX9586AZK+ pinout, MAX9586AZK+ application, or MAX9586AZK+ equivalent, key selection criteria include its SOT23-5 automotive temperature rating, DC-coupled 75Ω drive capability, input clamp level (300mV), bias voltage (500mV), and differential gain/phase performance (0.1% / 0.4°) critical for NTSC/PAL video fidelity.
Technical Context
The MAX9586AZK+ integrates a fixed-gain (2V/V) video amplifier, an 8.5MHz ±1dB reconstruction lowpass filter, and an active sync-tip clamp that sets input DC level to 300mV for composite video signals. Its BiCMOS process enables stable operation across -40°C to +125°C while maintaining <2% DC gain matching and <9ns group delay distortion.
It accepts AC-coupled inputs, supports both DC- and AC-coupled outputs (to 75Ω or 150Ω loads), and features shutdown control (SHDN pin) reducing supply current to <1µA. The device drives two 75Ω loads only when VDD > 3.135V; otherwise, it supports one DC-coupled or AC-coupled load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7V to 3.6V single supply - enables direct interface with 3.3V video DACs and low-power portable/automotive systems. |
| Supply Current | 4.25mA per channel - ensures minimal power draw in multi-channel video signal chains. |
| Passband Flatness | ±1dB up to 8.5MHz - preserves luminance detail and color fidelity across full SDTV bandwidth (NTSC: 4.2MHz, PAL: 5MHz). |
| Stopband Attenuation | 55dB at 27MHz - suppresses aliasing artifacts from 27MHz oversampled DAC outputs per ITU-R BT.601. |
| Differential Gain/Phase | 0.1% / 0.4° at 4.43MHz - meets broadcast-grade color accuracy requirements for CVBS decoding. |
| Sync-Tip Clamp Level | 300mV nominal - establishes precise black-level reference for composite video signals independent of source DC bias. |
| Bias Voltage | 500mV nominal - sets optimal DC operating point for chroma subcarrier inputs to minimize distortion. |
Pinout & Package
MAX9586AZK+ is housed in a RoHS-compliant 5-pin Thin SOT23 package (2.9mm × 1.6mm), rated for -40°C to +125°C operation. The package supports surface-mount reflow and requires 0.1µF VDD-to-GND bypassing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Common return path for all internal circuits; must be low-impedance connection to system ground plane. |
| 2 - OUT | Video output | Amplified, filtered CVBS/luma signal; capable of driving 75Ω DC-coupled or 150Ω AC-coupled loads. |
| 3 - IN | Video input | AC-coupled composite video or luma input; internally clamped to 300mV sync-tip level. |
| 4 - SHDN | Active-low shutdown | Pulling low reduces supply current to <1µA and places output in high-impedance state - enables power gating in multi-channel systems. |
| 5 - VDD | Positive supply | 2.7V–3.6V input; must be bypassed with 0.1µF capacitor to GND near the pin to suppress PSRR-induced noise. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated sync-tip clamp | Automatically restores DC level of AC-coupled CVBS signals to 300mV, eliminating need for external DC restoration circuitry. |
| 8.5MHz ±1dB reconstruction filter | Meets SDTV anti-aliasing requirements without external passive components, reducing board space and tuning complexity. |
| 2V/V fixed gain | Compensates for typical 0.5Vpp DAC output swing to deliver standard 1Vpp CVBS signal level into 75Ω load. |
| Automotive temperature range | Guaranteed operation from -40°C to +125°C - qualified for infotainment and display modules in passenger compartments. |
| Low 4.25mA quiescent current | Enables use in always-on video monitoring paths without compromising system thermal budget or battery life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video filter amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9587AZT+T | Dual-channel, 6-pin SOT23, identical electrical specs per channel - shares same filter, clamp, and gain architecture. | Requires PCB layout change for dual CVBS/luma paths (e.g., dual-tuner STBs); not pin-compatible with MAX9586AZK+. | Select when consolidating two video channels onto one IC to reduce footprint and interconnect complexity. |
| LMH0387SQ/NOPB | Single-channel, 3.3V-only, no integrated clamp; requires external DC restoration; higher 6.5mA supply current. | Limited to commercial temp range (-40°C to +85°C); lacks automotive qualification and sync-tip clamp functionality. | Consider only if system already implements external clamping and does not require -40°C to +125°C operation. |
Compared with MAX9587AZT+T, MAX9586AZK+ saves board area in single-channel designs and simplifies thermal management; compared with LMH0387SQ/NOPB, MAX9586AZK+ eliminates external clamp components and extends temperature coverage for automotive deployments.

FAQ
What is the maximum video signal bandwidth supported by the MAX9586AZK+?
The MAX9586AZK+ supports standard-definition video signals with a ±1dB passband flatness up to 8.5MHz. This exceeds the bandwidth requirements of NTSC (4.2MHz) and PAL (5MHz) broadcast standards and accommodates oversampled DVD video signals up to 6.75MHz, ensuring full fidelity for ITU-R BT.601-compliant sources. The 55dB attenuation at 27MHz prevents aliasing from 27MHz DAC clocks.
Can the MAX9586AZK+ drive a 75Ω load with DC coupling?
Yes, the MAX9586AZK+ can drive a single 75Ω load with DC coupling when VDD ≥ 3.135V (e.g., 3.3V nominal supply), delivering 2.1VPP output swing. At lower supplies (e.g., 2.7V), DC coupling is limited to one 75Ω load or AC coupling to a 150Ω load is required. The output stage is rail-to-rail capable with ~300mV headroom from each rail, and internal level-shifting fixes the sync tip at ~300mV at the output.
How does the sync-tip clamp function in the MAX9586AZK+?
The MAX9586AZK+ sync-tip clamp automatically sets the DC level of AC-coupled composite video (CVBS) or luma inputs to 300mV using internal circuitry - no external components required. It senses the sync pulse tip and adjusts the input baseline accordingly, enabling compatibility with video sources of unknown DC bias. Clamping current is specified at 1–2µA, and maximum input source resistance is 300Ω to maintain accuracy.
Is the MAX9586AZK+ suitable for automotive applications?
Yes, the MAX9586AZK+ is fully qualified for automotive use with guaranteed operation over -40°C to +125°C ambient temperature and AEC-Q100 stress testing alignment. Its BiCMOS process, integrated functions (clamp/filter/gain), and 4.25mA low quiescent current make it ideal for infotainment displays, backup cameras, and digital dashboards where thermal stability and reliability are critical. The SOT23-5 package supports automated assembly and reflow.
What is the shutdown behavior of the MAX9586AZK+?
When the SHDN pin of the MAX9586AZK+ is pulled low, the device enters shutdown mode, drawing less than 1µA supply current and placing the OUT pin in a high-impedance state. This allows dynamic power gating in multi-channel systems without affecting signal integrity on adjacent channels. The shutdown transition time is fast enough for frame-synchronized blanking, and the device resumes normal operation within microseconds after SHDN returns high.
