ad9000

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 comparator 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 compliant MIL-STD-883 Class B devices.
