DESCRIPTION
The ADC12L080 is a monolithic CMOS analog-to- digital converter capable of converting analog input
signals into 12-bit digital words at 80 Megasamples
per second (MSPS). This converter uses a
differential, pipeline architecture with digital error
correction and an on-chip sample-and-hold circuit to minimize die size and power consumption while
providing excellent dynamic performance. The
ADC12L080 can be operated with either the internal
or an external reference. Operating on a single 3.3V
power supply, this device consumes just 425 mW at
80 MSPS, including the reference current. The Power
Down feature reduces power consumption to just 50
mW.
The differential inputs provide a full scale input swing
equal to ±VREF. The buffered, high impedance, single•
ended external reference input is converted on-chip
to a differential reference for use by the processing
circuitry. Output data format may be selected as
either offset binary or two's complement.
This device is available in the 32-lead LQFP package
and operates over the industrial temperature range of
−40°C to +85°C.
