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

Voltage sense lines are provided to ensure accurate driving of

the

±V

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.
