DESCRIPTION
The ADC14DS080 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). The
digital outputs are serialized and provided on
differential LVDS signal pairs. 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 ADC14DS080
may be operated from a single +3.0V or 3.3V 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
accept a 2V full scale differential input swing. A stable
1.2V internal voltage reference is provided, or the
ADC14DS080 can be operated with an external 1.2V
reference. Output data format (offset binary versus
2's complement) and duty cycle stabilizer are
selectable. The duty cycle stabilizer maintains
performance over a wide range of clock duty cycles.
A serial interface allows access to the control
registers for full control of the ADC14DS80
functionality. The ADC14DS080 is available in a 60-
lead WQFN package and operates over the industrial
temperature range of −40°C to +85°C.
