Features Single +3.3V supply operation Internal sample-and-hold Internal reference Outputs 2.4V to 3.6V compatible Power down mode Duty Cycle Stabilizer Multiplexed Output Mode Description The ADC12DL065 is a dual, low power monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 65 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 +3.3V power supply, the ADC12DL065 achieves 11.0 effective bits at nyquist and consumes just 360 mW at 65 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 ADC12DL065 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 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: This Design Kit (consisting of an Evaluation Board and this manual) is designed to ease evaluation and design-in of National Semiconductor's ADC12DL040 12-bit Analog-to-Digital Converter, which operates at speeds up 40 Msps. The evaluation board can be used in either of two modes. In the Manual mode, suitable test equipment can be used with the board to evaluate the ADC12DL040 performance. In the Computer mode, evaluation is simplified by connecting the board to the WaveVision Data Capture Board (order number WAVEVSN BRD 4.0 or later), which is connected to a personal computer through a USB port and running WaveVision4 software, operating under Microsoft Windows. The software can perform an FFT on the captured data upon command and, in addition to a frequency domain plot, shows dynamic performance in the form of SNR, SINAD, THD, SFDR and ENOB. Features: Board comes fully assembled and tested Choice of ADC internal or board mounted reference On-board clock Single (+5V) supply needed All ADC features can be exercised Contents: Evaluation Board User's Guide ADC12DL040 Data Sheet
