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 DO – D7 8 8 Master Slave Register 8 8 Buffer Current Switch 8 6 Resistor 3 COMP AOUT 4 REF Copyright 1990, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
