Function
18
21
AGND
Analog Ground. Ground reference for track-and-hold, reference and DAC.
19
23
REF OUT
Voltage Reference Output. The internal 3 V reference is provided at this pin. The external load capability is
500 μA.
20
24
VIN
Analog Input. The analog input range is ±3 V for the AD7870, ±10 V for the AD7876, and 0 V to +5 V for the
AD7875.
21
25
VSS
Negative Supply, 5 V ± 5%.
22
26
12/8/CLK
Three Function Input. Defines the data format and serial clock format. With this pin at +5 V, the output
data for-mat is 12-bit parallel only. With this pin at 0 V, either byte or serial data is available and SCLK is
not continuous. With this pin at 5 V, either byte or serial data is again available but SCLK is now
continuous.
23
27
CONVST
Convert Start. A low to high transition on this input puts the track-and-hold into its hold mode and
starts conversion. This input is asynchronous to the CLK input.
24
28
CS
Chip Select. Active low logic input. The device is selected when this input is active. With CONVST tied
low, a new conversion is initiated when CS goes low.
