CXA3086Q

6-bit 140MSPS Flash A/D Converter

Description

The CXA3086Q is an 6-bit high-speed flash A/D

converter capable of digitizing analog signals at the

maximum rate of 140MSPS. ECL, PECL or TTL can

be selected as the digital input level in accordance

with the application. The TTL digital output level

allows 1: 2 demultiplexed output.

48 pin QFP (Plastic)
