DA1804NT
1-In, 4-Out Video Distribution Amplifier

The  DA1804NT is a 1-In, 4-Out  Distribution 
Amplifier designed to allow the connection of a 
single video source to as many as four display or 
recording devices.

The DA1804NT can pass NTSC, PAL, and SECAM 
composite video signals. It can also pass 
high-resolution monochrome computer video, such 
as grayscale signals used in medical imaging. The 
DA1804NT can handle video signals with levels up 
to 1.5 Vp-p.

State-of-the-art  technology gives the  DA1804NT a 
bandwidth of 350 MHz with a very flat frequency 
response up to 200MHz. It also offers a differential 
gain of 0.15% and a differential phase of 0.15 
degrees.

The DA1804NT Distribution Amplifier has a pre-set 
gain of 0 dB;

each output is completely 

independent and can withstand shorts to ground. 
Extremely rugged and compact, the DA1804NT fits 
easily into tight spots. Using high-quality 75 ohm 
coaxial cable, it can drive an NTSC signal 400 ft 
(122 m) or more.

Specifications are subject to change.
