VP215
Dual 90MHz 6-Bit Analog to Digital Converter
Preliminary Information
DS4068 - 1.4 May 1996
The VP215 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 VP215 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 VP215 also has the necessary bias voltages for the
reference resistor chain in the 'flash' architecture of the ADC.
