Standard-Definition Video Filter Amplifiers with
Dual SPST Switches
General Description
The MAX9517/MAX9524 are low-power video amplifiers
with integrated reconstruction filters. Specially suited for
standard-definition video signals, such as composite and
luma, these devices are ideal for a wide range of appli-
cations such as cell phones and security/CCTV cameras.
Video signals should be DC-coupled into the MAX9517
input and AC-coupled into the MAX9524 input.
The MAX9517/MAX9524 have two single-pole, single-
throw (SPST) analog switches that can be used to route
stereo audio, video, or digital signals. The reconstruc-
tion filter typically has ±1dB passband flatness at 9MHz
and 52dB attenuation at 27MHz. The amplifiers have a
gain of 2V/V, and the outputs can be DC-coupled to a
load of 75Ω, which is equivalent to two video loads. The
outputs can be AC-coupled to a load of 150Ω, which is
equivalent to one video load.
The MAX9517/MAX9524 operate from a 2.7V to 3.6V
single supply and are specified over the -40°C to
+125°C automotive temperature range. The MAX9517/
MAX9524 are available in a small 12-pin TQFN (3mm x
3mm) package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
