It converts digital signals to analog signals at a sampling rate of dc to 20 MHz. Because of such high-speed capability, the TL5602 is suitable for digital video applications such as digital television, video processing with a computer, and radar signal processing. The TL5602C is characterized for operation from 0°C to 70°C. functional block diagram 10 CLK Master Slave Register 8 Buffer 8 Current Switch 8 Resistor 6 AOUT DO – D7 8 8 3 COMP 4 REF PRODUCTION DATA information is current as of publication date.
