Check for Samples: ADC12C080 FEATURES DESCRIPTION The ADC12C080 is a high-performance CMOS
analog-to-digital converter capable of converting
analog input signals into 12-bit digital words at rates
up to 80 Mega Samples Per Second (MSPS). This
converter uses 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 ADC12C080 may be operated from a
single +3.0V power supply and consumes low power.
A separate +2.5V supply may be used for the digital
output interface which allows lower power operation
with reduced noise. 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 ADC12C080 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 …
