Function
1

DIN
Data In. Logic input. The channel to be converted is provided on this input and is clocked into an
internal register on the falling edge of SCLK.
2
3
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 AD7911/AD7921’s conversion process.
3
2
CS
Chip Select. Active low logic input. This input provides the dual function of initiating conversions on
the AD7911/AD7921 and framing the serial data transfer.

1
DOUT
Data Out. Logic output. The conversion result from the AD7911/AD7921 is provided on this output as a
serial data stream. The bits are clocked out on the falling edge of the SCLK signal.
For the AD7921, the data stream consists of two leading zeros; the channel identifier bit, which
identifies the channel that the conversion result corresponds to; followed by an invalid bit that
matches up to the channel identifier bit; followed by the 12 bits of conversion data, with MSB first.
For the AD7911, the data stream consists of two leading zeros; the channel identifier bit, which
identifies the channel that the conversion result corresponds to; followed by an invalid bit that
matches up to the channel identifier bit; followed by the 10 bits of conversion data, with MSB first and
two trailing zeros.
5
8
VDD
Power Supply Input. The VDD range for the AD7911/AD7921 is from 2.35 V to 5.25 V.
6
7
GND
Analog Ground. Ground reference point for all circuitry on the AD7911/AD7921. All analog input
signals should be referred to this GND voltage.
7, 8
6, 5
VIN0, VIN1
Analog Inputs. These two single-ended analog input channels are multiplexed into the on-chip track-
and-hold amplifier. The analog input channel to be converted is selected by writing to the third MSB
on the DIN pin. The input range is 0 to VDD.
