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 outputs 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 75W loads.
