DESCRIPTION
The ADC12DS080 is a high-performance CMOS
analog-to-digital converter capable of converting two
analog input signals into 12-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. This converter uses 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. The ADC12DS080 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 ADC12DS080
can be operated with an external 1.2V reference. The
selectable duty cycle stabilizer maintains
performance over a wide range of clock duty cycles.
A serial interface allows access to the internal
registers for full control of the ADC12DS080's
functionality. The ADC12DS080 is available in a 60-
lead WQFN package and operates over the industrial
temperature range of −40°C to +85°C
