General Description

The MAX9502 small, low-power video amplifier with inte-

grated reconstruction filter operates from a supply voltage

as low as 2.5V. The small size and the low minimum sup-

ply voltage make the MAX9502 ideal for portable applica-

tions 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-

toanalog 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 150Ω 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 5.3mAquiescent 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.
