EVALUATION KIT AVAILABLE MAX9502 2.5V Video Amplifier with Reconstruction Filter General Description The MAX9502 small, low-power video amplifier with integrated reconstruction filter operates from a supply voltage as low as 2.5V. The small size and the low minimum supply voltage make the MAX9502 ideal for portable applications or small, low-power applications. The MAX9502 DC-couples the input and the output, resulting in a very small solution. The MAX9502 input can be directly connected to the output of a video digitaltoanalog converter (DAC). The reconstruction filter is implemented as a 4th-order Chebyshev with a minimum passband of 5.5MHz, 3dB attenuation at 8MHz, and 55dB attenuation at 27MHz. The output amplifier provides a closed-loop gain of +6dB (MAX9502G) or +12dB (MAX9502M), and can drive a 2VP-P video signal into a 150 load to ground. The output signal is level-shifted so the sync tip is 110mV (typ) above ground. The MAX9502 operates from a 2.5V to 3.6V single supply and consumes only 5.3mA quiescent supply current. An active-low shutdown mode reduces the supply current to 0.01A. The MAX9502 is available in tiny 6-pin DFN (1mm x 1.5mm x 0.8mm) and 5-pin SC70 packages. The device is specified over the -40C to +85C extended and -40C to +125C automotive temperature ranges.

The MAX9502 consists of a lowpass filter and an output video buffer capable of driving a standard 150 video load to ground. The MAX9502G output buffer provides a fixed gain of +6dB, while the MAX9502M output buffer provides a fixed gain of +12dB. Filter The MAX9502 contains a 4th-order Chebyshev reconstruction filter. The Chebyshev-type response features a 0.4dB flat passband for NTSC and PAL signals. The stopband offers 55dB (typ) of attenuation at 27MHz and above (see the Typical Operating Characteristics). Output Amplifier The MAX9502G features a +6dB gain, while the MAX9502M features a +12dB gain. Operating from a 2.5V to 3.0V supply, the output amplifier is able to drive a 2V signal into a 150 video load to ground. Operating from a 3.0V to 3.6V supply, the output amplifier is able to drive a 2.4VP-P signal into a 150 video load to ground. The output is typically offset 110mV above ground to guarantee linear operation of the amplifier. The MAX9502 output only sources current; all loads should be connected to ground. Short-Circuit Protection The MAX9502 typical application circuit includes a 75 back-termination resistor that limits short-circuit currents for an external short applied at the video output. The MAX9502 features internal output short-circuit protection to prevent device damage in prototyping and applications where the amplifier output can be directly shorted. Short-circuit protection activates if the output is shortcircuited and the output current exceeds 95mA. During short-circuit protection, the output of the MAX9502 is shut off for 12s and then turns on for 0.8s. If the short is still present, the MAX9502 output shuts off again. Extended short circuits result in a pulsed output. The device resumes normal operation after the short is removed. www.maximintegrated.com Applications Information Input Considerations The MAX9502 input is DC-coupled. When the supply voltage is between a 2.5V and 3V supply, the input voltage range extends from ground to 1.05V for the MAX9502G and from ground to 0.525V for the MAX9502M. When the supply voltage is between 3V and 3.6V, the input voltage range extends from ground to 1.2V for the MAX9502G and from ground to 0.6V for the MAX9502M. The MAX9502G accepts a composite video signal with a sync tip from 0 to 50mV and the MAX9502M accepts a composite video signal with a sync tip from 0 to 25mV. A typical currentoutput DAC that operates from a single supply usually creates a composite video signal with a sync tip very close to ground. Hence, the DAC output can be directly connected to the MAX9502 input. Keep the board trace as short as possible to minimize parasitic stray capacitance and prevent unintentional high-frequency attenuation. Output Considerations The MAX9502 output must be DC-coupled. No AC-coupling capacitors are allowed. The MAX9502 connects directly to the video cable through a 75 series backtermination resistor. The other end of the cable should be properly terminated with a 75 resistor as well. Because of this configuration, the peak-to-peak amplitude as well as the DC level of the signal is divided by two. The MAX9502 output signal is level-shifted up so the sync tip is around 110mV. Power-Supply Bypassing and Layout Considerations The MAX9502 operates from a single-supply voltage down to 2.5V, allowing for low-power consumption. Bypass VCC to GND with a 0.1F capacitor. Place all external components as close to the device as possible.
