Description The ADC14DC080 is a high-performance CMOS analog-to-digital converter capable of converting two analog input signals into
14-bit digital words at rates up to 80 Mega Samples Per Second (MSPS). These converters use a differential, pipelined architecture
with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component
count, while providing excellent dynamic performance. A unique sample-and-hold stage yields a full-power bandwidth of 1 GHz.
The ADC14DC080 may be operated from a single +3.0V power supply. A power-down feature reduces the power consumption to very
low levels while still allowing fast wake-up time to full operation. The differential inputs provide a 2V full scale differential
input swing. A stable 1.2V internal voltage reference is provided, or the ADC14DC080 can be operated with an external 1.2V
reference. Output data format (offset binary versus 2's complement) and duty cycle stabilizer are pin-selectable. The duty
cycle stabilizer maintains performance over a wide range of clock duty cycles.
The ADC14DC080 is available in a 60-lead LLP package and operates over the industrial temperature range of −40°C to +85°C.
