Mnemonic
Function
6
CS
Chip Select. Active low logic input. This input provides the dual function of initiating con-
versions on the AD7466/AD7467/AD7468 and also frames the serial data transfer.
1VDD
Power Supply Input. The VDD range for the AD7466/67/68 is from +1.8 V to +3.6 V.
2
G N D
Analog Ground. Ground reference point for all circuitry on the AD7466/AD7467/AD7468.
All analog input signals should be referred to this GND voltage.
3VIN
Analog Input. Single-ended analog input channel. The input range is 0 to VDD.
5
SDATA
Data Out. Logic Output. The conversion result from the AD7466/AD7467/AD7468 is pro-
vided 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 AD7466 consists of four leading zeros followed
by the 12 bits of conversion data which is provided MSB first. The data stream for the
AD7467 consists of four leading zeros followed by 10 bits of data. The datastream for the
AD7468 consists of four leading zeros followed by 8 bits of data.
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 AD7466/AD7467/AD7468 conver-
sion process.

NOTES
1Linearity Error here refers to integral linearity error.
2RT = SOT-23, RM =
SOIC.
3This can be used as a stand-alone evaluation board or in conjunction with the EVAL-CONTROL BOARD for evaluation/demonstration purposes.
4This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators.
