ADC14DC080/ADC14DC105
Dual 14-Bit, 80/105 MSPS A/D Converter with CMOS
Outputs
General Description
NOTE: This is Advance Information for products current-
ly in development. ALL specifications are design targets
and are subject to change.
The ADC14DC080 and ADC14DC105 are high-performance
CMOS analog-to-digital converters capable of converting two
analog input signals into 14-bit digital words at rates up to
80/105 Mega Samples Per Second (MSPS) respectively.
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 com-
ponent count, while providing excellent dynamic perfor-
mance. A unique sample-and-hold stage yields a full-power
bandwidth of 1 GHz. The ADC14DC080/105 may be operated
from a single +3.3V power supply. A power-down feature re-
duces the power consumption to very low levels while still
allowing fast wake-up time to full operation. The differential
inputs provide a 2V full scale differential input swing. A stable
1.2V internal voltage reference is provided, or the AD-
C14DC080/105 can be operated with an external 1.2V refer-
ence. Output data format (offset binary versus 2's comple-
ment) and duty cycle stabilizer are pin-selectable. The duty
cycle stabilizer maintains performance over a wide range of
clock duty cycles.
The ADC14DC080/105 is available in a 60-lead LLP package
and operates over the industrial temperature range of −40°C
to +85°C.
