ADC14DS080
Dual 14-Bit, 80 MSPS A/D Converter with Serial LVDS
Outputs
General Description
The ADC14DS080 is a high-performance CMOS analog-to-
digital converter capable of converting two analog input sig-
nals 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 cor-
rection 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 con-
sumption 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 al-
lows 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 tem-
perature range of −40°C to +85°C.
