14-Bit, 5 MSPS, Military A/D Converter
The HI5905N/QML is a monolithic, 14-bit, 5MSPS Analog-
to-Digital Converter fabricated in an advanced BiCMOS
process. It is designed for high speed, high resolution
applications where wide bandwidth, low power consumption
and excellent SINAD performance are essential. With a
100MHz full power input bandwidth and high frequency
accuracy, the converter is ideal for many Military types of
communication systems employing digital IF architectures.
The HI5905N/QML is designed in a fully differential pipelined
architecture with a front end differential-in-differential-out
sample-and-hold amplifier (S/H). Consuming 350mW (typ)
power at 5MSPS, the HI5905N/QML has excellent dynamic
performance over the full Military temperature range.
Data output latches are provided which present valid data to
the output bus with a data latency of only 4 clock cycles.
Specifications for QML devices are controlled by the
Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HI5905N/QML
are contained in SMD 5962-98591. That document may
be easily downloaded from our website.
