The MAX9516 is a video signal amplifier that operates at 1.8V from a single power supply. It is characterized by low power consumption and DirectDrive technology. It can drive a 2VP-P video signal into a 150Ω load and reduce power consumption when no load is present. The MAX9516 also has the ability to detect and report changes in the video load, helping to reduce overall system power consumption. It utilizes DirectDrive technology, which includes an integrated charge pump and internal linear regulator to create a clean negative power supply, allowing the amplifier to set the output video black level near ground. The MAX9516 also features an internal reconstruction filter that smooths the video signal and reduces spikes and steps from the video digital-to-analog converter.
The MAX9516 video filter amplifier operates from a single 1.8 V supply and consumes only 6 mW quiescent power (12 mW average). It uses Maxim’s DirectDrive™ technology to drive a 2 Vp‑p video signal into a 150 Ω load while keeping the video black level near ground. The device includes an internal charge pump, linear regulator, and a five‑pole Butterworth reconstruction filter (±1 dB flatness to 7.5 MHz).
The amplifier features a fixed gain of 8, DC‑coupled input/output, a transparent sync‑tip clamp, and a video load‑detect pin (LOAD) that reduces power to 31 pW when no load is present. It is supplied in a 10‑lead HDFN package and is intended for digital cameras, mobile phones, security cameras, and automotive video applications.
