1 VDD Power Supply Input. The VDD range for the AD7476-EP is from 2.35 V to 5.25 V. 2 GND Analog Ground. Ground reference point for all circuitry on the part. All analog input signals should be referred to this GND voltage. 3 VIN Analog Input. Single-ended analog input channel. The input range is 0 V to VDD. 4 SCLK Serial Clock. Logic input. SCLK provides the serial clock for accessing data from the part. This clock input is also used as the clock source for the AD7476-EP conversion process. 5 SDATA Data Out. Logic output. The conversion result is provided on this output as a serial data stream. The bits are clocked out on the falling edge of the SCLK input. The data stream from the AD7476-EP consists of four leading zeros followed by the 12 bits of conversion data; this is provided MSB first. 6 CS Chip Select. Active low logic input. This input provides the dual function of initiating conversions on the AD7476-EP and framing the serial data transfer.
