MAX9502GEXK+T

P1-P3P4-P6P7-P9P10-P11
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 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 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 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 5.3mA 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.

Note 1: All devices are 100% production tested at T
A
= +25°C. Specifications over temperature limits are guaranteed by design.
Note 2: DC voltage gain (A
V
) is a two-point measurement in which the output voltage swing is divided by the input voltage swing.
Note 3: Short-circuit current is the trip current for the protection. During the protection, OUT is switched alternatively on and off.
