Low (45 pF) Input Capacitance
MIL-STD-883-Compliant Versions Available
Radar Warning/Guidance Systems
The 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 TTL-compatible, making the AD9020
an ideal candidate for use in low power systems. An over-
flow bit is provided to indicate analog input signals greater
Voltage sense lines are provided to insure accurate driving of the
± VREF 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. Two performance grades for temperatures of both
0°C to 70°C and –55°C to +125°C ranges are offered to allow
the user to select the linearity best suited for each application.
Dynamic performance is fully characterized and production
tested at 25°C. MIL-STD-883 units are available.
The AD9020 A/D Converter is available in versions compliant
with MIL-STD-883. Refer to the Analog Devices Military Prod-
ucts Databook or current AD9020/883B data sheet for detailed
