CXA1977R

CXA1977R 10-bit 20MSPS A/D Converter Description The CXA1977R is a 10-bit 20MSPS 2-step parallel type A/D converter for video signal processing. This A/D converter operates on +5V power supplies. The analog signal can be converted to the digital signal by using this IC in conjunction with the Sample-and-hold IC. Features Maximum operating speed : 20MSPS (Min.) Resolution : 10-bit Low power dissipation : 160mW (Typ.) Wide-band analog input : 10MHz Low input capacitance : 50pF (Typ.) Built-in digital correction (Compensation within ±16LSB) TTL input TTL output Output code : binary/2'S complement/1'S complement Block Diagram VREFBS VREFB VREF3 VREF2 VREF1 VREFT VREFTS N.C. N.C.
