CXD1172AM

CXD1172AM/AP 6-bit 20MSPS Video A/D Converter (CMOS) Description CXD1172AM/AP is a 6-bit CMOS A/D converter for video use. The adoption of a 2-step parallel system achieves low consumption at a maximum conversion speed of 20MSPS minimum, 35MSPS typical. Features Resolution: 6-bit ± 1/2LSB Max. sampling frequency: 20MSPS Low power consumption: 40mW (at 20MSPS typ.) (Reference current excluded) Built-in sampling and hold circuit. 3-state TTL compatible output. Power supply: 5V single Low input capacitance: 4pF Reference impedance: 250Ω (typ.) Applications TV, VCR digital systems and a wide range of fields where high speed A/D conversion is required.
