1mm x 1mm Video Filter Amplifier with Automatic Shutdown and 4V/V Gain

Packaged in a 1mm x 1mm UCSP™ with 4 bumps, the MAX9519 is an ultra-small standard-definition video filter amplifier with automatic shutdown.

The automatic shutdown circuitry eliminates the need for a shutdown control. This feature provides intelligent power management by disabling the filter and output amplifier in the absence of a video input signal and/or an output video load. At shutdown, the device consumes only 1.8µA.

The MAX9519 features an internal reconstruction filter that smooths the steps and reduces the spikes on the video signal from the video digital-to-analog converter (DAC). The reconstruction filter typically has ±1dB passband flatness to 9MHz and typically 48.5dB of attenuation at 27MHz.

The video input to the MAX9519 can be directly connected to the DAC output. The MAX9519 has an internal fixed gain of 4V/V and expects a nominal full-scale video input signal of 0.5VP-P. The MAX9519 is specified to operate over the -40°C to +125°C automotive temperature range.
