The ADC12DL040 is a dual, low power monolithic CMOS analog-to-digital converter capable
of converting analog input signals into 12-bit digital words at 40 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 250 MHz Full Power Bandwidth. Operating on a single +3.0V power supply, the
ADC12DL040 achieves 11.1 effective bits at nyquist and consumes just 210 mW at 40 MSPS, including
the reference current. The Power Down feature reduces power consumption to 36 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. The digital outputs from the two ADC's
are available on a single multiplexed 12-bit bus or on separate buses. 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
ADC12DL040 can be connected to a separate supply voltage in the range of 2.4V to the analog supply
This device is available in the 64-lead TQFP package and will operate over the industrial
temperature range of −40°C to +85°C. An evaluation board is available to ease the evaluation
