GENERAL DESCRIPTION
The AD9000 is a 6-bit, high speed, analog-to-digital converter
with ECL compatible outputs and a bipolar input stage. The
AD9000 is fabricated in a high performance bipolar process that
allows encode rates up to 77 MSPS.
The AD9000 employs the standard flash converter architecture
based on 64 individual comparators which simultaneously
determine the precise analog signal level. The comparators are
followed by two stages of decoding logic, allowing the AD9000
to operate with a very low error rate. The low 35 pF input
capacitance of the AD9000 greatly simplifies the analog driver
stage. An overflow output bit is also incorporated into the
AD9000 design as is a hysteresis control pin to modify compara-
tor sensitivity.

The AD9000 is offered as both a commercial temperature range
device, 0 C to +70 C, and as an extended temperature range
device, –55 C to +125 C. Both versions are available packaged
in a 16-pin ceramic DIP. The extended temperature range
device is also available in a 28-pin ceramic LCC package. The
extended temperature range versions are offered as fully compli-
ant MIL-STD-883 Class B devices.
