The MAX9502G dual-package evaluation kit (EV kit) is a convenient platform for evaluating the performance of the MAX9502G or MAX9502M video filter amplifiers in both µDFN and SC70 packages. The input and output (I/O) signals from the MAX9502G dual-package EV kit are DC-coupled. The MAX9502G dual-package EV kit's input terminal has a 75Ω termination to ground, and the output has a 75Ω back-termination resistor. The MAX9502G has a gain of 2V/V (+6dB) and the MAX9502M has a gain of 4V/V (+12dB). The MAX9502G dual-package EV kit operates from a single 2.5V to 3.6V power supply.
The MAX9502G/MAX9502M is a small, low-power, video filter amplifier that operates from a supply voltage as low as 2.5V. The filter passband is set for standard definition video. The small size and low minimum supply voltage make the MAX9502G/MAX9502M ideal for portable applications such as mobile phones, digital still cameras, and camcorders.
The MAX9502G/MAX9502M does not require coupling capacitors or bias networks, resulting in an extremely small footprint solution. The MAX9502G/MAX9502M input can be directly connected to the output of a video digital-to-analog converter (DAC). The reconstruction filter is implemented as a 4th-order Chebyshev and has +1dB passband flatness to 5.5MHz, 3dB attenuation at 8MHz, and 55dB attenuation at 27MHz.
The output amplifier drives a 2VP-P video signal into a 150Ω load to ground. The output signal is level-shifted so the sync tip is typically 110mV above ground.
The MAX9502G/MAX9502M consumes only 5.3mA quiescent supply current. An active-low shutdown mode reduces the supply current to 10nA. The MAX9502G dual-package EV kit is available in tiny 6-pin µDFN (1mm x 1.5mm x 0.72mm) and 5-pin SC70 (2mm x 2.2mm x 0.95mm) packages. The device is specified over the -40°C to +85°C extended temperature range and -40°C to +125°C automotive temperature range. The MAX9502G dual-package EV kit can also be used to evaluate the MAX9502M by replacing the IC.
