June 1994
6-Bit, 30 MSPS Flash A/D Converter
Features
Description
• This Circuit is Processed in Accordance to MIL-STD-
883 and is Fully Conformant Under the Provisions of
Paragraph 1.2.1.
• 30 MSPS with No Missing Codes
• 20MHz Full Power Input Bandwidth
• No Missing Codes Over Temperature
• Sample and Hold Not Required
• Single +5V Supply Voltage
• CMOS/TTL
• Overflow Bit
The HI-5701/883 is a monolithic, 6-bit, CMOS Flash Analog-
to-Digital Converter. It is designed for high speed
applications where wide bandwidth and low power
consumption are essential. Its 30 MSPS speed is made
possible by a parallel architecture which also eliminates the
need for an external sample and hold circuit. The HI-5701/
883 delivers ±0.7 LSB differential nonlinearity while
consuming only 250mW (typical) at 30 MSPS. Microproces-
sor 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 7-bit
resolution.
