Maxim Integrated Products Inc. introduced the MAX9515, claimed as the industry's smallest, lowest pin-count video filter amplifier for SD video connections from portable devices to TVs.

Packaged in a 1mm x 1mm, 4-bump UCSP, the MAX9515 features the company's proprietary SmartSleep technology, which reduces current consumption to 5?amps in shutdown mode. The MAX9515 is ideal for low-power, space-constrained portable applicationscellphones, digital still or video cameras, and portable media playersthat require a video output to a SDTV.

The MAX9515 combines an active-filter stage with a video amplifier to band-limit the signal and set the video-output level to drive a TV connection. Featuring a higher-order filter than competitive devices, it achieves much better attenuation of high-frequency artifacts and noise in the video-output signal, according to Maxim. The integrated fifth-order filter features 1dB passband flatness up to 9MHz and 50dB attenuation at 27MHz, ensuring signal integrity in ultracompact designs.
