ADC14DS105
Dual 14-Bit, 105 MSPS A/D Converter with Serial LVDS
Outputs
General Description
The ADC14DS105CISQ and ADC14DS105AISQ are high-
performance 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 dig-
ital outputs are serialized and provided on differential LVDS
signal pairs. Both parts provide excellent performance, how-
ever, the ADC14DS105AISQ offers higher SFDR. These con-
verters 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 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 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.
