Description
The HI3050 is a triple, 10-bit D/A converter, fabricated in a
silicon gate CMOS process, ideally suited for RGB video
applications.
The converter incorporates three 10-bit input data registers
with a common blanking capability, forcing all outputs to 0mA.
The HI3050 features low glitch, high impedance current out-
puts and single 5V supply operation. Low current inputs
accept standard TTL/CMOS levels. The architecture is a
current cell arrangement providing low differential and integral
linearity errors.
The HI3050 requires a 2V external reference and a set
resistor to control the output current. The HI3050 also features
a chip enable/disable pin for reducing power consumption
(<5mW) when the part is not in use.
The HI3050 can generate RS-343A and RS-170 compatible
video signals into doubly terminated and singly terminated
75Ω loads.
