Product details
Overview
The MAX9532AUB+ from Maxim Integrated is a DirectDrive® video filter amplifier designed for automotive infotainment systems, featuring integrated short-to-battery protection (up to 18V), 4V/V fixed gain, DC-coupled input/output, and an internal 5-pole Butterworth reconstruction filter with ±1dB passband flatness to 9.5MHz. It operates from a single 3.3V supply and shifts video black level near ground without output coupling capacitors.
For engineers reviewing the MAX9532AUB+ datasheet, MAX9532AUB+ pinout, MAX9532AUB+ application, or MAX9532AUB+ equivalent, this page delivers verified technical context, automotive-grade thermal performance (-40°C to +125°C), exact pin functionality, real-world video signal conditioning behavior, and validated alternative options for video DAC interface design.
Technical Context
The MAX9532AUB+ integrates a charge pump and linear regulator to generate a clean negative supply (CPVSS) enabling sync-tip drive below ground while maintaining <40pVs glitch impulse. Its internal 5-pole Butterworth lowpass filter provides 42dB attenuation at 27MHz and supports full-scale 0.5VP-P input signals with 2VP-P output swing into 100Ω.
Short-to-battery protection activates via JACKSENSE input when output voltage exceeds 8V threshold, disabling the output switch within 10µs; recovery time is 4.9–20ms after fault removal. The transparent sync-tip clamp maintains DC bias stability across AC- or DC-coupled inputs with ≤3.3µA clamping current and ≤300Ω max source resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V single supply - enables direct integration with 3.3V automotive domain controllers without LDO overhead. |
| Fixed Gain | 4V/V (3.92–4.08V/V over temp) - precisely scales 0.5VP-P DAC output to standard 2VP-P composite video level. |
| Reconstruction Filter | 5-pole Butterworth, ±1dB flat to 9.5MHz, 42dB attenuation at 27MHz - suppresses DAC imaging artifacts without phase distortion. |
| Short-to-Battery Protection | Withstands 18V shorts on OUT; detects via JACKSENSE; disconnects in 10µs - eliminates need for external TVS or fuse in head-unit video outputs. |
| Operating Temperature | -40°C to +125°C - qualified for under-dash automotive placement with no derating up to 125°C ambient. |
| Quiescent Current | 15–23mA - enables low-power standby modes in always-on infotainment gateways. |
| Differential Gain/Phase | 0.7% / 0.5° at 4.43MHz - meets NTSC/PAL broadcast-grade color fidelity requirements for rear-seat displays. |
Pinout & Package
The MAX9532AUB+ is housed in a 3mm × 3mm, 10-pin µMAX® package (package code U10+2), optimized for space-constrained automotive PCB layouts with exposed pad thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Positive power supply input | Bypassed with 1µF capacitor to GND; supplies core logic, amplifier, and charge pump; must be stable within 3.0–3.6V. |
| 2 C1P | Charge-pump flying capacitor positive terminal | Connects to one end of 1µF ceramic flying cap; forms charge-transfer path for negative rail generation. |
| 3 CPGND | Charge-pump ground reference | Must be tied directly to system GND; separates noisy charge-pump return from analog ground paths. |
| 4 C1N | Charge-pump flying capacitor negative terminal | Connects to other end of same 1µF flying cap; completes charge inversion loop with C1P. |
| 5 CPVSS | Negative power supply output | Provides filtered -2V rail for amplifier output stage; bypassed with 1µF || 10nF to GND for low-noise operation. |
| 6 VSS | Negative supply connection | Internally tied to CPVSS; must be connected externally to CPVSS to enable DirectDrive functionality. |
| 7 OUT | Video output driver | Delivers 2VP-P composite video; includes series switch for short-to-battery protection; drives 75Ω/100Ω loads. |
| 8 JACKSENSE | Battery short detection input | Monitors output connector voltage; triggers protection when >8V above GND; requires 50Ω back-termination resistor. |
| 9 GND | Analog ground reference | Primary ground return for video signal path; must be star-connected to minimize noise coupling into IN/OUT. |
| 10 IN | Video input terminal | Accepts 0.5VP-P DC- or AC-coupled video; features transparent sync-tip clamp with 2–3.3µA pull-down current. |
Key Features
| Feature | Design Value |
|---|---|
| DirectDrive® architecture | Eliminates 220–3000µF DC-blocking capacitors at output by generating internal negative rail, reducing BOM cost and board area by >80%. |
| Integrated reconstruction filter | 5-pole Butterworth response ensures ±1dB gain flatness to 9.5MHz and 42dB stopband attenuation at 27MHz - removes DAC sampling artifacts without post-filter tuning. |
| Short-to-battery protection | Withstands 18V faults on OUT pin with sub-10µs response via JACKSENSE comparator - replaces discrete protection circuitry in automotive video routing. |
| Transparent sync-tip clamp | Automatically stabilizes DC bias for AC-coupled inputs using ≤3.3µA clamp current and ≤300Ω source impedance - enables interoperability with legacy video sources. |
| DC-coupled I/O | Supports both DC- and AC-coupled inputs without external components; black level shifted to near 0V at OUT - simplifies timing alignment in multi-DAC systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video filter amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9531AUB+ | No short-to-battery protection; identical pinout, gain, and filter specs; lacks JACKSENSE input and internal output switch. | Suitable only for protected internal video paths (e.g., PCB-to-PCB), not for connector-facing outputs. | Select MAX9531AUB+ only when external protection is already implemented and space allows omission of fault detection circuitry. |
| THS7314DR | 3-channel, 3.3V video amp with 6dB gain; no integrated reconstruction filter or DirectDrive; requires external negative supply. | Used in multi-channel RGB/YUV systems; lacks automotive qualification and short-to-battery resilience. | Choose THS7314DR for non-automotive, multi-channel designs where external filtering and dual supplies are acceptable. |
Compared with MAX9532AUB+, MAX9531AUB+ reduces cost and complexity where battery shorts are absent, while THS7314DR offers channel density at the expense of automotive robustness and integrated filtering - neither matches the MAX9532AUB+'s combination of DirectDrive, 18V fault tolerance, and broadcast-grade video fidelity in a single 10-pin µMAX package.

FAQ
What is the operating temperature range specified for the MAX9532AUB+?
The MAX9532AUB+ is specified for continuous operation from -40°C to +125°C, meeting AEC-Q100 Grade 2 automotive qualification requirements. This range covers under-hood and under-dash environments without thermal derating, and junction temperature is limited to +150°C per absolute maximum ratings.
Does the MAX9532AUB+ require external capacitors for its charge pump?
Yes, the MAX9532AUB+ requires two external 1µF ceramic capacitors: one between C1P and C1N (pins 2 and 4) for charge transfer, and a second 1µF || 10nF network from CPVSS (pin 5) to GND for noise filtering. These are mandatory for DirectDrive functionality and stable negative rail generation.
How does the transparent sync-tip clamp function in the MAX9532AUB+?
The transparent sync-tip clamp in the MAX9532AUB+ automatically engages for AC-coupled inputs by pulling the IN pin toward ground with ≤3.3µA current, preventing negative excursions beyond the input range. For DC-coupled signals above ground, it remains inactive - preserving signal integrity without added offset or distortion.
Can the MAX9532AUB+ drive a standard 75Ω video load?
Yes, the MAX9532AUB+ is characterized driving 100Ω loads to GND but supports 75Ω termination via external back-termination resistor (e.g., 50Ω in series with 75Ω load). Output voltage swing remains ≥1.96VP-P at 3.0V supply, satisfying composite video amplitude standards with margin.
What is the purpose of the JACKSENSE pin on the MAX9532AUB+?
The JACKSENSE pin on the MAX9532AUB+ monitors the video output connector voltage to detect short-to-battery faults. When voltage exceeds ~8V, it triggers internal output switch disablement within 10µs, protecting the device from damage during 12V/24V automotive battery shorts up to 18V.
