VP211

VP211 Dual 90MHz 6-Bit Analog to Digital Converter Preliminary Information DS4476 - 1.1 May 1996 The VP211 is a dual 90MHz 6-bit Analog to Digital Converter designed for use in consumer satellite receivers and decoders, video systems, multimedia and communications applications. Operating from a single +5V supply, the VP211 includes an on-chip high bandwidth ADC driver amplifier, a 6-bit ADC and digital I/O that can be interfaced to either +5V or +3V. The VP211 also has the necessary bias voltages for the reference resistor chain in the 'flash' architecture of the ADC. CLKIN VCCD DGND VRT COMPA VINA AGND VCCA VRM COMPB VINB VRB N.C.
