    • Description

    The ADC12DL080 is a dual, low power monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 80 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 600 MHz Full Power Bandwidth. Operating on a single +3.3V power supply, the ADC12DL080 achieves 11.0 effective bits at Nyquist and consumes just 447mW at 80 MSPS. The Power Down feature reduces power consumption to 50 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. 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 ADC12DL080 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 ADC12DL080 12-bit Analog-to-Digital Converter, which operates at speeds up 80 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
    ADC12DL080 performance. In the Computer mode, evaluation is simplified by connecting the board to the WaveVision Data
    Capture Board (order number WAVEVSN BRD 4.0), 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
