The ADC14L020 is a low power monolithic CMOS analog-to-digital converter capable of
converting analog input signals into 14-bit digital words at 20 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 power consumption while providing excellent dynamic performance
and a 150 MHz Full Power Bandwidth. Operating on a single +3.3V power supply, the ADC14L020
achieves 12.0 effective bits at nyquist and consumes just 150 mW at 20 MSPS . The Power Down
feature reduces power consumption to 15 mW.
The differential inputs provide a full scale differential input swing equal to 2 times
VREF with the possibility of a single-ended input. Full use of the
differential input is recommended for optimum performance. Duty cycle stabilization and output data
format are selectable using a quad state function pin. The output data can be set for offset binary
or two's complement.
To ease interfacing to lower voltage systems, the digital output driver power pins of the
ADC14L020 can be connected to a separate supply voltage in the range of 2.4V to the analog supply
voltage.
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 ease the evaluation
process.
