General Description
The 10-bit pipelined analog-to-digital converter provides a maximum sample rate of 40MS/s with low power consumption of 11mW from a core-supply voltage of 1.5V. For power-savings a power-down mode is available. The analog inputs are differential for high noise
immunity and allow a large voltage-swing of ±900mV. The device possesses an internal voltage reference which can be bypassed to use external references to meet higher
accuracy requirements of the system. For data acquisition the IP-core has a parallel tri-state output which works with logic levels of up to 3.3V. In a stand-alone version the ADC contains an SPI interface with internal FIFO for timing-tolerant communication.
