1. Describe

The AD7918BRUZ-REEL7 are 10-bit, high-speed, low-power, 8-channel, successive approximation ADC. These parts operate from a single 2.7 V to 5.25 V supply Power and functional throughput up to 1 MSPS. Components Contains a Low Noise, Wide Bandwidth Track-and-Hold Amplifier Can handle input frequencies in excess of 8 MHz. Transformation process and data collection usage controls CS and serial clock signals for easy device interface with microprocessor or DSP. The input signal is sampled at The falling edge of CS and conversion are also initiated at this time. There is no pipeline delay associated with this part. The AD7918BRUZ-REEL7 use advanced design techniques to Very low power consumption at maximum throughput. At maximum throughput, the AD7918BRUZ-REEL7 2 mA maximum when using a 3 V supply; when using a 5 V supply, Current consumption is 2.7 mA maximum. Configured through the control register, the analog input The device can be selected from 0 V to REFIN or 0 V to 2 × REFIN with direct binary or two's complement output coding. The AD7918BRUZ-REEL7 each feature eight single-ended analog inputs and a channel sequencer, allowing Preprogrammed selection of channels converted in sequence. The conversion time for the AD7918BRUZ-REEL7 is determined by the SCLK frequency, which is also used as master clock to control conversions.
