DESCRIPTION
The ADC12L066 is a monolithic CMOS analog-to-
digital converter capable of converting analog input
signals into 12-bit digital words at 66 Megasamples
per second (Msps), minimum, with typical operation
possible up to 80 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. A unique
sample-and-hold stage yields a full-power bandwidth
of 450 MHz. Operating on a single 3.3V power
supply, this device consumes just 357 mW at 66
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 ±V_REF with the possibility of a single-ended
input. Full use of the differential input is
recommended for optimum performance. For ease of
use, the buffered, high impedance, single-ended
reference input is converted on-chip to a differential
reference for use by the processing circuitry. Output
data format is 12-bit offset binary.
This device is available in the 32-lead LQFP package
and will operate over the industrial temperature range
of −40°C to +85°C. An evaluation board is available
to facilitate the evaluation process.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
