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.
