Product details
Overview
The MAX9532AUB+T 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 a 5-pole Butterworth reconstruction filter with ±1dB passband flatness to 9.5MHz. It operates from a single 3.3V supply and delivers 2VP-P output from a 0.5VP-P DAC input while maintaining sync-tip below ground.
For engineers reviewing the MAX9532AUB+T datasheet, MAX9532AUB+T pinout, MAX9532AUB+T application, or MAX9532AUB+T equivalent, key selection criteria include short-to-battery survival capability, DirectDrive elimination of output coupling capacitors, DC-coupled signal path compatibility, automotive temperature range (–40°C to +125°C), and reconstruction filter performance at 27MHz (42dB attenuation).
Technical Context
The MAX9532AUB+T integrates a charge pump and linear regulator to generate a clean negative supply (CPVSS) enabling true DC-coupled video output with black level near ground and sync pulled below 0V. Its internal 5-pole Butterworth lowpass filter provides precise frequency shaping for composite video signals.
Short-to-battery protection uses a comparator monitoring JACKSENSE to detect >8V overthreshold at the output connector, disabling an internal series switch within 10µs. Recovery time after short removal is 4.9ms to 20ms depending on duration, and the device sustains 18V fault conditions without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V single supply - enables direct use with standard automotive 3.3V rails without level-shifting circuitry. |
| Fixed Gain | 4V/V ±2% - ensures consistent 2VP-P output from 0.5VP-P DAC input across temperature (–40°C to +125°C). |
| Reconstruction Filter | ±1dB flatness to 9.5MHz, 42dB attenuation at 27MHz - suppresses DAC imaging artifacts while preserving NTSC/PAL luminance bandwidth. |
| Short-to-Battery Protection | Withstands 18V output shorts - eliminates need for external TVS diodes in automotive head unit and display interface designs. |
| Output Voltage Swing | 2.744VP-P min (VDD = 3.135V), 1.96VP-P min (VDD = 3.0V) into 100Ω - meets full-scale video amplitude requirements under worst-case supply conditions. |
| Differential Gain/Phase | 0.7% / 0.5° - maintains color fidelity in analog composite video transmission paths. |
| Quiescent Current | 15mA to 23mA - supports low-power operation in always-on vehicle infotainment modules. |
Pinout & Package
The MAX9532AUB+T is housed in a 3mm × 3mm, 10-pin µMAX® package rated for –40°C to +125°C operation, optimized for space-constrained automotive PCB layouts.
| 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. |
| 2 C1P | Charge-pump flying capacitor positive terminal | Connects to one end of 1µF ceramic flying capacitor (C1); forms charge-transfer node for negative rail generation. |
| 3 CPGND | Charge-pump ground reference | Must be tied directly to system GND; isolates charge-pump noise from analog ground plane. |
| 4 C1N | Charge-pump flying capacitor negative terminal | Connects to other end of 1µF flying capacitor (C1); completes charge-pump inversion cycle. |
| 5 CPVSS | Negative power supply output | Provides filtered –1.8V rail for output stage; bypassed with 1µF || 10nF to GND for low-noise operation. |
| 6 VSS | Negative supply connection | Internally tied to CPVSS; must be externally connected to CPVSS for proper biasing of output stage. |
| 7 OUT | Filtered video output | DC-coupled 2VP-P output driving 75Ω/100Ω loads; includes short-to-battery protected switching element. |
| 8 JACKSENSE | Battery fault detection input | Monitors output connector voltage; triggers protection when >8V above GND (e.g., short to 12V battery). |
| 9 GND | Analog ground reference | Primary return path for video signal and internal bias currents; must be star-connected to minimize noise coupling. |
| 10 IN | Video input | Accepts 0.5VP-P DC- or AC-coupled composite video; includes transparent sync-tip clamp for AC-input DC bias correction. |
Key Features
| Feature | Design Value |
|---|---|
| DirectDrive architecture | Eliminates 220µF–3000µF output coupling capacitors by generating internal negative rail, reducing board area and cost in space-constrained automotive displays. |
| Integrated 5-pole Butterworth filter | Provides precise frequency response control (±1dB to 9.5MHz) to smooth DAC steps and suppress aliasing without external components. |
| Transparent sync-tip clamp | Automatically corrects DC offset on AC-coupled inputs using only 2µA clamping current, preserving signal integrity without manual biasing. |
| Short-to-battery protection | Survives sustained 18V output shorts via fast-acting internal switch (10µs response), removing need for external protection circuitry in harsh automotive environments. |
| DC-coupled I/O | Enables stable black-level referencing at ground and sync-tip below ground, eliminating baseline drift caused by RC time constants in AC-coupled 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+T | Lacks short-to-battery protection; identical pinout and DirectDrive functionality. | Suitable only in protected environments where output shorts to >8V are impossible. | Select MAX9531AUB+T only if automotive battery fault exposure is eliminated by mechanical or system-level design. |
| THS7353IPWPR | 3-channel, 3.3V/5V dual-supply operation; no integrated charge pump or short-to-battery protection. | Requires external negative supply and discrete protection; broader channel count but higher BOM cost. | Choose THS7353IPWPR when multi-channel video routing is needed and system-level protection is already implemented. |
Compared with MAX9531AUB+T and THS7353IPWPR, the MAX9532AUB+T uniquely combines automotive-grade short-to-battery resilience, single-supply DirectDrive operation, and integrated reconstruction filtering in a 10-pin µMAX package-enabling simplified, robust, and space-efficient composite video interfaces.

FAQ
What is the operating temperature range for the MAX9532AUB+T?
The MAX9532AUB+T is specified for continuous operation from –40°C to +125°C, meeting automotive under-hood and display module thermal requirements. This rating is validated per AEC-Q100 stress test conditions and applies across all electrical parameters in the datasheet, including gain accuracy, filter response, and short-to-battery protection threshold stability.
Does the MAX9532AUB+T require external capacitors for its charge pump?
Yes, the MAX9532AUB+T requires two external 1µF ceramic capacitors: one between C1P and C1N (pins 2 and 4) for charge transfer, and one between CPVSS and GND (pin 5) for negative rail filtering. The CPVSS bypass must also include a parallel 10nF low-ESL capacitor to suppress high-frequency charge-pump noise that could degrade video signal integrity.
How does the short-to-battery protection in the MAX9532AUB+T function?
The MAX9532AUB+T monitors output voltage via the JACKSENSE pin (pin 8). When voltage exceeds ~8V above GND-indicating a short to battery-the internal comparator disables a series output switch within 10µs. The device survives up to 18V continuously and resumes normal operation 4.9ms–20ms after the short is removed, depending on fault duration.
Can the MAX9532AUB+T accept AC-coupled video inputs?
Yes, the MAX9532AUB+T features a transparent sync-tip clamp on the IN pin (pin 10) that automatically corrects DC offset on AC-coupled inputs using only 2µA clamping current. This allows direct connection of legacy AC-coupled DAC outputs without external bias networks, while maintaining full 0.5VP-P signal swing and minimal distortion.
What is the purpose of the CPGND pin on the MAX9532AUB+T?
The CPGND pin (pin 3) serves as the dedicated ground reference for the internal charge pump circuitry. It must be connected directly to system GND but kept physically separate from analog signal ground planes to prevent charge-pump switching noise from coupling into the video output. Improper CPGND routing degrades PSRR and introduces visible glitches in the video waveform.
