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 digital-to-analog
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 0.01µA.
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.
