HI5905N/QML

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.
