The ADC14DS105CISQ and ADC14DS105AISQ are highperformance
CMOS analog-to-digital converters capable of
converting two analog input signals into 14-bit digital words at
rates up to 105 Mega Samples Per Second (MSPS). The digital
outputs are serialized and provided on differential LVDS
signal pairs. Both parts provide excellent performance, however,
the ADC14DS105AISQ offers higher SFDR. 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. The
ADC14DS105 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 ADC14DS105 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 ADC14DS105's functionality.
The ADC14DS105 is available in a 60-lead LLP package and
operates over the industrial temperature range of ?40°C to
+85°C.
