General Description

Packaged in a 1mm x 1mm UCSP™ with 4 bumps, the

MAX9519 is an ultra-small standard-definition video fil-

ter 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 con-

sumes 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 con-

nected to the DAC output. The MAX9519 has an inter-

nal fixed gain of 4V/V and expects a nominal full-scale

video input signal of 0.5V

P-P

. The MAX9519 is specified

to operate over the -40°C to +125°C automotive tem-

perature range.
