MAX9532AUB+

Video Amps And Modules Overview

The MAX9532AUB+ 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 features an internal fixed gain of 4V/V, processing a nominal 0.5VP-P input to produce a 2VP-P output. It includes a five-pole Butterworth reconstruction filter providing ±1dB passband flatness up to 9.5MHz and 42dB attenuation at 27MHz. Integrated short-to-battery protection withstands output shorts up to 18V. The component is housed in a 10-pin µMAX package and specified over the -40°C to +125°C temperature range.

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 voltage exceeds the threshold, protecting against shorts up to 18V.
• Internal reconstruction filter smooths DAC output steps and reduces spikes, ensuring signal integrity without external components.
• Transparent sync-tip clamp allows AC-coupling of input signals with varying DC biases while maintaining signal stability.

Video Amps And Modules Applications

• Automotive infotainment systems
• Video signal conditioning for display interfaces
• Harsh environment video amplification

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. Ensure the procurement channel sources genuine Analog Devices/Maxim Integrated products. Confirm that the delivered units match the MAX9532AUB+ designation regarding the 10-pin µMAX form factor. Check for any automotive qualification markings if required for the specific application environment.

Video Amps And Modules Selection Notes

Select this component when space constraints prohibit large output coupling capacitors in video signal paths. It is suitable for applications requiring direct connection to video DACs with minimal external circuitry. Consider the 4V/V fixed gain and 3.3V single-supply operation requirements. Evaluate the need for short-to-battery protection in automotive wiring harnesses where jack insertion or faults may occur.

Video Amps And Modules Part Context

The MAX9532 belongs to Maxim's DirectDrive family of video amplifiers. This series addresses the limitations of traditional AC-coupled video buffers by integrating negative supply generation on-chip. The AUB+ variant specifically denotes the lead-free/RoHS-compliant version in the 10-pin µMAX package, intended for high-volume manufacturing in automotive and consumer electronics.

Video Amps And Modules Replacement Considerations

The MAX9532AUB/V+T is the automotive-qualified equivalent within the same package and specification set. Verify pin compatibility and electrical characteristics before substituting non-qualified variants. No other cross-model replacements are documented in the provided datasheet.
