The ADC14DS080 is a high-performance CMOS analog-todigital
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 sampleand-
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 LLP package and operates over the industrial temperature
range of −40°C to +85°C.
