GENERAL DESCRIPTION
The AD9060 A/D converter is a 10-bit monolithic converter
capable of word rates of 75 MSPS and above. Innovative
architecture using 512 input comparators instead of the tradi-
tional 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
Voltage sense lines are provided to ensure accurate driving of
the ± V
voltages applied to the units. Quarter point taps on
REF
the resistor ladder help optimize the integral linearity of the unit.
The AD9060 is available in a 68-lead ceramic leaded (gull wing)
chip carrier package specifically designed for low thermal imped-
ances. 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.
