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 mini-
mum supply voltage make the MAX9502 ideal for
portable applications such as mobile phones, digital
still cameras, and camcorders.
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 imple-
mented 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 2V
P-P
video signal into a 150鈩?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 0.01碌A(chǔ).
The MAX9502 is available in tiny 6-pin 碌DFN (1mm x
1.5mm x 0.8mm) and 5-pin SC70 packages. The
device is specified over the -40擄C to +85擄C extended
temperature range.
