GENERAL DESCRIPTION
The Analog Devices' MATV series of AID converters represent
a major breakthrough in high-speed AID technology. Providing
conversion word rates from dc to 11MHz, 16MHz and 20MHz
the MATV-0811, MATV-0816 and MATV-0820 are the lowest
cost AID converters in their performance class. As complete
devices, they require only the addition of external power to
accomplish precision video AID conversion.
The use of internal hybrid microcircuit construction allows
these modular AID's to occupy a volume of only 21 cubic inches.
They are housed in metal cases which not only shield the circuits from external RF interference, but aid in efficient heat.
dissipation. A choice of analog input voltages is available, including the industry standard 0 to + 1V at 7SQ. The encode
command input, data ready output, and the digital bit outputs
are all TTL compatible. Designed to operate from either :!:12V
or :!:lSV analog and +SV digital supplies (MATV-o811 and
MATV-o816 also require -S.2V), the MATV series dissipate
less than 8 watts. Their weight is < 10 ounces due to enclosure
rather than encapsulation. This technique facilitates rapid,
inexpensive factory repair and aids in reliable printed circuit
board mounting by the customer without extensive mechanical constraints or system engineering.
Relative dc accuracy is 0.2% of full scale :!:l/2LSB when operating over the frequency range of dc to 20MHz. The MATV
series is designed to digitize color television signals at rates
up to 20MHz and is also ideally suited for other analog to
digital conversion requirements, such as radar signal processing,
laser pulse analysis, transient analysis, and medical electronics
applications where real-time analysis and display of large quantities of information are required.

INFORMATION
series AID converter will be calibrated at :!:15V
Order by model number either MATV-0811 ,
or MATV-o820.
OBS
Optional Versions
The MATV series AID's are available with a variety of options,
including analog input range and impedance, encode command
input impedance, encode word rate, power supply voltage calibration, etc. Any option other than what is shown on the data
sheet will have longer delivery, since each non-standard device
is built on a per order basis.

Device Marking
The MATV series AID that you order will be marked with a
series of alphanumerics which specifically designate the options
built into the device. For the standard devices, these will be as
follows:
MATV -0811 will be marked MATV -0811-1-B IN-l 5 for older
devices, or MATV-0811-AAI50 for newer devices.
MATV-0816 will be marked MATV-0816-0175 BIN 75143150
for older devices, or MATV-0816 ABBAI43150 for newer
devices.
MATV-0820 will be marked MATV-0820-0175 BIN 75 for
older devices, or MATV-0820 ABAA for newer devices.

A complete listing of optional designators is available from
either the factory or your local Analog Devices' sales office.

This information is provided so that there will be no confusion
as to why information other than the basic model number appears on the device identification label, which might cause
