T he AD9020 A/D converter is a 10-bit monolithic converter
capable of word rates of 60 MSPS and above. Innovative archi-
tecture using 512 input comparators instead of the traditional
1024 required by other flash converters reduces input capaci-
tance and improves linearity.
Encode and outputs are T T L-compatible, making the AD9020
an ideal candidate for use in low power systems. An overflow
bit is provided to indicate analog input signals greater than

SENSE
.
Voltage sense lines are provided to insure accurate driving of the

voltages applied to the units. Quarter-point taps on the
resistor ladder help optimize the integral linearity of the unit.
Either 68-pin ceramic leaded (gull wing) packages or ceramic
LCCs are available and are specifically designed for low thermal
impedances. T wo performance grades for temperatures of both
