Overview
a 10-Bit 60 MSPS A/D Converter AD9020 FEATURES Monolithic 10-Bit/60 MSPS Converter TTL Outputs Bipolar (؎1.
75 V) Analog Input 56 dB SNR @ 2.
3 MHz Input Low (45 pF) Input Capacitance MIL-STD-883-Compliant Versions Available APPLICATIONS Digital Oscilloscopes Medical Imaging Professional Video Radar Warning/Guidance Systems Infrared Systems GENERAL DESCRIPTION The AD9020 A/D converter is a 10-bit monolithic converter capable of word rates of 60 MSPS and above.
Innovative architecture using 512 input comparators instead of the traditional 1024 required by other flash converters reduces input capacitance and improves linearity.
Encode and outputs are TTL-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 +VSENSE.
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 Products Databook or current AD9020/883B data sheet for detailed specifications.
