Function
Power Supply Input. The V
DD
range for the AD7940 is from 2.5 V to 5.5 V.
Analog Ground. Ground reference point for all circuitry on the AD7940. 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
DD
.
Serial Clock. Logic input. SCLK provides the serial clock for accessing data from this part. This clock
input is also used as the clock source for the AD7940's conversion process.
Data Out. Logic output. The conversion result from the AD7940 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
AD7940 consists of two leading zeros followed by 14 bits of conversion data that are provided MSB
first. This will be followed by four trailing zeroes if CS is held low for a total of 24 SCLK cycles. See the
Serial Interface section.
Chip Select. Active low logic input. This input provides the dual function of initiating conversions on
the AD7940 and framing the serial data transfer.
No Connect. This pin should be left unconnected.
