GENERAL DESCRIPTION
The AD9060 A/D converter is a 10-bit monolithic converter ca-
pable of word rates of 75 MSPS and above. Innovative architec-
ture using 512 input comparators instead of the traditional 1024
required by other flash converters reduces input capacitance and
improves linearity.
Inputs and outputs are ECL-compatible, which makes the
AD9060 the recommended choice for systems with conversion
rates >30 MSPS to minimize system noise. An overflow bit is
provided to indicate analog input signals greater than +V
SENSE
.
Voltage sense lines are provided to ensure accurate driving of
the ±V
REF
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 specifically designed for low thermal im-
pedances. 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 AD9060 A/D converter is available in versions compliant
with MIL-STD-883. Refer to the Analog Devices Military Prod-
ucts Databook or current AD9060/883B data sheet for detailed
specifications.
