The MAX9519 is a video filter amplifier from TI with automatic shutdown. The product is packaged in a 1mm x 1mm UCSP, which is very small. The automatic shutdown circuit eliminates the need for a shutdown controller. 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.
The MAX9519 is an ultra‑small, standard‑definition video filter amplifier packaged in a 1 mm × 1 mm UCSP with four bumps. It provides automatic shutdown to reduce power consumption when no video input or load is present, and it operates from a single 2.7 V‑3.6 V supply.
Key features include a fixed 4 V/V gain, a reconstruction filter with +1 dB flatness to 9 MHz and 48.5 dB attenuation at 27 MHz, and operation over an automotive temperature range of –40 °C to +125 °C. The device is intended for mobile phones, digital still cameras, camcorders and other space‑constrained applications.
