Standard-Definition Video Filter Amplifiers with

Dual SPST Switches

General Description Features

The MAX9517/MAX9524 are low-power video amplifiers Integrated Reconstruction Filter for Standard- with integrated reconstruction filters. Specially suited for

Definition Video

standard-definition video signals, such as composite and

luma, these devices are ideal for a wide range of appli- 9MHz, ±1d B Passband

cations such as cell phones and security/CCTV cameras.

52d B Attenuation at 27MHz

Video signals should be DC-coupled into the MAX9517

input and AC-coupled into the MAX9524 input. Dual SPST Switches

The MAX9517/MAX9524 have two single-pole, single- Fixed Gain of 2V/V throw (SPST) analog switches that can be used to route

DC- or AC-Coupled Output

stereo audio, video, or digital signals. The reconstruc- tion filter typically has ±1d B passband flatness at 9MHz 2.7V to 3.6V Single-Supply Operation and 52d B 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 Applications

outputs can be AC-coupled to a load of 150Ω, which is

equivalent to one video load.

Mobile Phones/Cell Phones

The MAX9517/MAX9524 operate from a 2.7V to 3.6V

single supply and are specified over the -40°C to Digital Still Cameras (DSC)

+125°C automotive temperature range. The MAX9517/

Camcorders (DVC)

MAX9524 are available in a small 12-pin TQFN (3mm x

Portable Media Players (PMP)

3mm) package.
