●The ADC14L040 is a low power monolithic CMOS analog-to-digital converter capable of converting analog input signals into 14-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 150 MHz Full Power Bandwidth. Operating on a single +3.3V power supply, the ADC14L040 achieves 11.9 effective bits at nyquist and consumes just 235 mW at 40 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 ADC14L040 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.
