MAX9532AUB+T

Video Amps And Modules Overview

The MAX9532AUB+T is a DirectDrive video filter amplifier designed for automotive environments. It operates from a 3V to 3.6V single supply with a typical quiescent current of 23mA. The device provides an internal fixed voltage gain of 4V/V, converting a nominal 0.5VP-P input to a 2VP-P output. It features a five-pole Butterworth reconstruction filter offering ±1dB passband flatness up to 9.5MHz and 42dB attenuation at 27MHz. Integrated short-to-battery protection allows the output to withstand shorts up to 18V.

Video Amps And Modules Feature Summary

• DirectDrive technology eliminates large DC-blocking capacitors by setting the video black level near ground using an integrated charge pump and linear regulator.
• Integrated short-to-battery protection utilizes an internal switch to disconnect the output when voltages exceed the threshold, protecting against shorts up to 18V.
• Transparent sync-tip clamp enables AC-coupling of input signals with varying DC biases while preventing signal drift.
• Internal reconstruction filter smooths DAC output steps and reduces spikes to improve video signal quality.

Video Amps And Modules Applications

• Automotive infotainment systems
• Video DAC interfacing in harsh environments

Video Amps And Modules Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the '/V' designation if automotive qualification is required, as standard versions may differ. Ensure the component matches the 10-pin µMAX package dimensions. Check for lead-free/RoHS compliance status indicated by the '+' symbol. Validate that the operating temperature range meets the -40°C to +125°C requirement for the intended application environment.

Video Amps And Modules Selection Notes

Select this component when space constraints prohibit large output coupling capacitors. It is suitable for applications requiring direct connection to video DACs without external level shifting circuits. Consider the 4V/V fixed gain and 0.5VP-P input specification for signal matching. Evaluate the need for short-to-battery protection in automotive wiring harnesses. Ensure the power supply range aligns with the 3V to 3.6V operational limits.

Video Amps And Modules Part Context

The MAX9532 belongs to Maxim's DirectDrive family of video amplifiers. It integrates functions typically requiring multiple discrete components, including filtering, amplification, and protection. The µMAX package provides a compact footprint for space-sensitive designs. The device addresses common challenges in single-supply video processing by generating an internal negative rail.
