MAX9516ALB+

Video Amps And Modules Overview

The MAX9516ALB+T is a 1.8V ultra-low-power DirectDrive video filter amplifier with load detect, manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 1.7V to 2.625V supply and features an internal fixed gain of 8 V/V. The device consumes 6mW quiescent power and 12mW average power, dropping to 31μW in active-detect mode when no load is present. It includes a five-pole Butterworth reconstruction filter with ±1dB passband flatness up to 7.5MHz and 46dB attenuation at 27MHz. The output drives a 2VP-P signal into a 150Ω load using integrated charge pump and linear regulator technology.

Video Amps And Modules Feature Summary

• DirectDrive technology eliminates large output-coupling capacitors and sets the video black level near ground.
• Integrated video load detection reduces system power consumption by entering low-power active-detect mode when no load is connected.
• Internal five-pole Butterworth reconstruction filter smooths DAC steps and attenuates high-frequency spikes.
• Transparent input sync-tip clamp allows AC-coupling of input signals with varying DC biases.

Video Amps And Modules Applications

• Digital Still Cameras (DSC)
• Digital Video Cameras (DVC)
• Mobile Phones
• Portable Media Players (PMP)
• Security/CCTV Cameras

Video Amps And Modules Procurement Notes

Verify the specific suffix +T indicates tape and reel packaging for the MAX9516ALB+ variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range meets -40°C to +125°C requirements for the target application environment. Cross-reference the pin configuration L1022+1 package code with PCB footprint specifications.

Video Amps And Modules Selection Notes

Select this component for portable applications requiring low voltage operation and minimal power consumption. The fixed gain of 8 V/V accommodates video DAC outputs that cannot generate full-scale 1VP-P signals at lower supply voltages. The DirectDrive architecture is suitable for space-constrained designs where large coupling capacitors are undesirable. Verify compatibility with standard-definition video signal formats.

Video Amps And Modules Part Context

The MAX9516 represents Maxim’s second-generation DirectDrive video amplifiers, succeeding first-generation devices like the MAX9503/MAX9505. It addresses the industry shift toward 1.8V operation to eliminate 3.3V supplies in deep submicron processes. The device integrates a charge pump and linear regulator to create a clean negative supply, enabling the output stage to drive sync pulses below ground without external components.
