Description
Power Supply Input. The V
Analog Ground. Ground reference point for all circuitry on the part. All analog input signals should be referred
to this GND voltage.
Analog Input. Single-ended analog input channel. The input range is 0 V to V
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.
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.
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.
