Description

The MAX9502 small, low-power video amplifier withintegrated reconstruction filter operates from a supplyvoltage as low as 2.5V. The small size and the low minimumsupply voltage make the MAX9502 ideal forportable applications or small, low-power applications.The MAX9502 DC-couples the input and the output,resulting in a very small solution. The MAX9502 input canbe directly connected to the output of a video digital-to-analogconverter (DAC). The reconstruction filter is implementedas a 4th-order Chebyshev with a minimumpassband of 5.5MHz, 3dB attenuation at 8MHz, and55dB attenuation at 27MHz.The output amplifier provides a closed-loop gain of+6dB (MAX9502G) or +12dB (MAX9502M), and candrive a 2VP-P video signal into a 150Ω load to ground. The output signal is level-shifted so the sync tip is110mV (typ) above ground.The MAX9502 operates from a 2.5V to 3.6V single supplyand consumes only 5.3mA quiescent supply current.An active-low shutdown mode reduces the supplycurrent to 0.01µA.The MAX9502 is available in tiny 6-pin µDFN (1mm x 1.5mm x 0.8mm) and 5-pin SC70 packages. The device is specified over the -40°C to +85°C extended and -40°C to +125°C automotive temperature ranges.ApplicationsDigital Still CamerasMobile PhonesPortable VideoSecurity/CCTV
