CXA1977R Datasheet | Sony Semiconductor Solutions

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 : 160m W (Typ.) - Wide-band analog input : 10MHz - Low input capacitance : 50p F (Typ.) - Built-in digital correction (pensation within ±16LSB) - TTL input - TTL output - Output code : binary/2'S plement/1'S plement Block Diagram VREFBS VREFB VREF3 VREF2 VREF1 VREFT VREFTS N.C.
