2.5V Video Amplifier with Reconstruction Filter
General Description
Features
● Tiny 6-Pin μDFN (1mm x 1.5mm x 0.8mm) and 5-Pin
SC70 Packages
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.

DC-Coupled Input and Output Save Board Space
4-Pole Chebyshev Filter
5.5MHz Passband
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.
55dB Attenuation at 27MHz
0.01μA Low-Current Shutdown Mode
2.5V to 3.6V Single-Supply Operation
Video Amplifier with Fixed Gains of +6dB
(MAX9502G) or +12dB (MAX9502M)
Typical Operating Circuit
The output amplifier provides a closed-loop gain of +6dB
V
CC
(MAX9502G) or +12dB (MAX9502M), and can drive a 2V
P-P
video signal into a 150Ω load to ground. The output signal
0.1µF
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.

MAX9502
2.5V Video Amplifier with Reconstruction Filter
Detailed Description
Applications Information
The MAX9502 filters and amplifies the video DAC output
in applications such as digital still cameras and mobile
phones. The MAX9502 consists of a lowpass filter and
an output video buffer capable of driving a standard 150Ω
video load to ground. The MAX9502G output buffer pro-
vides a fixed gain of +6dB, while the MAX9502M output
buffer provides a fixed gain of +12dB.
Input Considerations
The MAX9502 input is DC-coupled. When the supply volt-
age 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 current-
output 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.
Filter
The MAX9502 contains a 4th-order Chebyshev recon-
struction filter. The Chebyshev-type response features a
0.4dB flat passband for NTSC and PAL signals. The stop-
band 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 150Ω video load to ground. Operating from a
3.0V to 3.6V supply, the output amplifier is able to drive a
Output Considerations
The MAX9502 output must be DC-coupled. No
AC-coupling capacitors are allowed. The MAX9502 con-
nects directly to the video cable through a 75Ω series
backtermination resistor. The other end of the cable
should be properly terminated with a 75Ω 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.
2.4V
signal into a 150Ω video load to ground. The out-
P-P
put 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 75Ω
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.
Power-Supply Bypassing and Layout
Considerations
The MAX9502 operates from a single-supply voltage
down to 2.5V, allowing for low-power consumption.
Short-circuit protection activates if the output is short-
circuited and the output current exceeds 95mA. During
short-circuit protection, the output of the MAX9502 is shut
off for 12μs and then turns on for 0.8μs. 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.
Bypass V

external components as close to the device as possible.
