Features 1.1 GHz Full Power Bandwidth Internal sample-and-hold circuit Low power consumption Internal precision 1.0V reference Single-ended or Differential clock modes Data Ready output clock Clock Duty Cycle Stabilizer Dual +3.3V and +1.8V supply operation (+/- 10%) Power-down mode Offset binary or 2's complement output data format 48-pin LLP package, (7x7x0.8mm, 0.5mm pin-pitch) Description The ADC14155 is a high-performance CMOS analog-to-digital converter capable of converting analog input signals into 14-bit digital words at rates up to 155 Mega Samples Per Second (MSPS). This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component count, while providing excellent dynamic performance. A unique sample-and-hold stage yields a full-power bandwidth of 1.1 GHz. The ADC14155 operates from dual +3.3V and +1.8V power supplies and consumes 967 mW of power at 155 MSPS. The separate +1.8V supply for the digital output interface allows lower power operation with reduced noise. A power-down feature reduces the power consumption to 5 mW with the clock input disabled, while still allowing fast wake-up time to full operation. The differential inputs provide a full scale differential input swing equal to 2 times the reference voltage. A stable 1.0V internal voltage reference is provided, or the ADC14155 can be operated with an external reference. The ADC14155 can be configured for either single-ended or differential operation. Clock mode (differential versus single-ended) and output data format (offset binary versus 2's complement) are pin-selectable. A duty cycle stabilizer maintains performance over a wide range of clock duty cycles. The ADC14155 is available in a 48-lead LLP package and operates over the industrial temperature range of −40°C to +85°C.

Description: This Design Kit is designed to ease evaluation and design-in of National Semiconductor's ADC14155 14-bit Analog-to-Digital Converter, which operates at speeds up 155 Msps. The evaluation is intended for evaluating input frequencies greater than 150 MHz. For input frequencies below 150 MHz, the ADC14155LFEB is recommended. 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 ADC14155 performance. In the Computer mode, evaluation is simplified by connecting the board to the WaveVision 4.4 or higher Data Capture Board, which is connected to a personal computer through a USB port and running WaveVision 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 Single (+5V) supply needed All ADC features can be exercised Contents: Evaluation Board User's Guide CD

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.
