MAX9532AUB/V+T

Video Amps And Modules Overview

The MAX9532AUB/V+T is a DirectDrive video filter amplifier designed for automotive environments. It operates from a single 3V to 3.6V supply and features an internal fixed gain of 4V/V, converting a nominal 0.5VP-P input to a 2VP-P output. The device integrates a five-pole Butterworth lowpass reconstruction filter providing ±1dB passband flatness up to 9.5MHz and 42dB attenuation at 27MHz. Integrated short-to-battery protection allows the output to survive shorts up to 18V. It utilizes DirectDrive technology to set the black level near ground without external coupling capacitors.

Video Amps And Modules Feature Summary

• DirectDrive architecture eliminates large DC-blocking capacitors by creating an internal negative supply via a charge pump and linear regulator.
• Integrated short-to-battery protection disconnects the output when voltage exceeds the threshold, safeguarding against battery shorts.
• Transparent sync-tip clamp enables AC-coupling of input signals with varying DC biases while maintaining signal integrity.
• Internal reconstruction filter smooths DAC output steps and reduces high-frequency spikes in the video signal.

Video Amps And Modules Applications

• Automotive infotainment systems
• Rear-seat entertainment displays
• Backup camera video processing

Video Amps And Modules Procurement Notes

Verify that the suffix 'V' confirms automotive qualification and 'T' indicates tape-and-reel packaging. Ensure the component matches the specific Maxim Integrated (Analog Devices) manufacturing source. Confirm RoHS compliance status based on the '+' designation in the part number. Validate the package type as 10-pin µMAX for physical compatibility.

Video Amps And Modules Selection Notes

Select this component when space constraints prohibit large output coupling capacitors required by traditional AC-coupled designs. It is suitable for applications requiring direct connection to video DACs with 0.5VP-P full-scale signals. Consider its 4V/V fixed gain and 9.5MHz bandwidth for standard definition video filtering needs in harsh automotive thermal environments.

Video Amps And Modules Part Context

This device belongs to the MAX9532 family of DirectDrive video amplifiers. It is specifically engineered for automotive safety and infotainment systems where reliability under harsh conditions is critical. The integration of short-to-battery protection and reconstruction filtering simplifies the design of video signal paths in vehicle display architectures.

Video Amps And Modules Replacement Considerations

The MAX9532AUB+ is a non-tape-and-reel equivalent. Verify pinout and electrical specifications before substituting other video amplifiers, as DirectDrive functionality and short-to-battery protection levels may vary across different models.

Video Amps And Modules FAQ

How does the DirectDrive technology handle the sync tip below ground?

The MAX9532 uses an integrated charge pump and linear regulator to create a clean negative power supply, allowing the amplifier to pull the sync tip below ground without external components.

What is the function of the JACKSENSE input?

The JACKSENSE input monitors the output connector to detect short circuits to battery voltage. If a short is detected above the threshold, it disables the internal switch to protect the device.

Can the MAX9532 accept AC-coupled inputs?

Yes, the transparent sync-tip clamp automatically clamps the input signal to ground, allowing AC-coupling of signals with different DC biases while preventing drift outside the input range.
