Features Choice of Binary or 2’s complement output format Single +3.3V Supply Operation Outputs 2.4V to 3.3V Compatible Pin Compatible with ADC12D040 Power Down Mode Internal/External Reference Description The ADC12DL066 is a dual, low power monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 66 Megasamples per second (Msps), minimum. 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 and a 450 MHz Full Power Bandwidth. Operating on a single 3.3V power supply, the ADC12DL066 achieves 10.7 effective bits and consumes just 686 mW at 66 Msps, including the reference current. The Power Down feature reduces power consumption to 75 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 ADCs are available on separate 12-bit buses with an output data format choice of offset binary or two’s complement. To ease interfacing to lower voltage systems, the digital output driver power pins of the ADC12DL066 can be connected to a separate supply voltage in the range of 2.4V to the digital supply voltage. 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 process.

Description: The ADC12DL066 is a Dual 12-Bit, 66 MSPS, 686 mW A/D Converter with internal reference and internal sample-and-hold and is offered in a 64-lead LQFP. It is designed to operate over the industrial temperature range of -40°C to +85°C. This evaluation board is designed to ease the evaluation and design-in of National Semiconductor`s dual 40 Msps ADC12DL066 Analog-to-Digital Converter. The board can be used in either of two modes. In the Manual or Stand-alone mode the board can be used with suitable test equipment to evaluate the ADC12DL066`s performance. In the Computer of Automatic mode, evaluation is simplified through easy data capture and upload to a PC by connecting this board to the WaveVision Digital Interface board (order number WAVEVSN BRD 4.0 or later), which is connected to a personal computer through a USB port and using National Semiconductor`s WaveVision software (version 4.0 or later) operating under Microsoft Windows. Alternatively, data capture board WaveVision4 data capture board may be used and connected to a personal computer through a USB port.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
