Function
Chip Select. Active low logic input. This input provides the dual function of initiating conversions on the AD7910/
AD7920 and framing the serial data transfer.
Power Supply Input. The V
Analog Ground. Ground reference point for all circuitry on the AD7910/AD7920. All analog input signals should be
referred to this GND voltage.
Analog Input. Single-ended analog input channel. The input range is 0 to V
Data Out. Logic output. The conversion result from the AD7910/AD7920 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 AD7920 consists
of four leading zeros followed by the 12 bits of conversion data, which is provided MSB first. The data stream from
the AD7910 consists of four leading zeros followed by the 10 bits of conversion data followed by two trailing zeros,
which is also provided MSB first.
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 AD7910/AD7920 conversion process.
