www.ti.com SNAS463B – SEPTEMBER 2008 – REVISED APRIL 2013 ADC14DC080 Dual 14-Bit, 80 MSPS A/D Converter with CMOS Outputs
Check for Samples: ADC14DC080 FEATURES DESCRIPTION The ADC14DC080 is a high-performance CMOS
analog-to-digital converter capable of converting two
analog input signals into 14-bit digital words at rates
up to 80 Mega Samples Per Second (MSPS). These
converters use a differential, pipelined architecture
with digital error correction and an on-chip sampleand-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 ADC14DC080 may be operated from a
single +3.0V 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 provide a 2V full scale
differential input swing. A stable 1.2V internal voltage
reference is provided, or the ADC14DC080 can be
operated with an external 1.2V reference. Output
data format (offset binary versus 2's complement)
and duty cycle stabilizer are pin-selectable. The duty
cycle stabilizer maintains performance over a wide
range of clock duty cycles. 1 2 Internal Sample-and-Hold Circuit and Precision
