HI-5700
Description
The HI-5700 is a monolithic, 8-bit, CMOS Flash Analog-to-
Digital Converter. It is designed for high speed applications
where wide bandwidth and low power consumption are
essential. Its 20 MSPS speed is made possible by a parallel
architecture which also eliminates the need for an external
sample and hold circuit. The HI-5700 delivers r0.5 LSB
differential nonlinearity while consuming only 725mW
(typical) at 20 MSPS. Microprocessor compatible data
output latches are provided which present valid data to the
output bus 1.5 clock cycles after the convert command is
received. An overflow bit is provided to allow the series
connection of two converters to achieve 9-bit resolution.
