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.
