NOTES

1. THE EXPOSED PAD IS CONNECTED INTERNALLY.

FOR INCREASED RELIABILITY OF THE SOLDER JOINTS

AND MAXIMUM THERMAL CAPABILITY, IT IS RECOMMENDED

2. NIC = NOT INTERNALLY CONNECTED.

17

CNV

Channel Cycle Input. When in round robin mode, the CNV pin is used to cycle through the selected channels.

18

GPO3

General-Purpose Output 3. This pin is a digital output.

19

SDO

Serial Data Output. This pin can be used for daisy chaining a number of these devices together or for reading

back the data stored in a register for diagnostic purposes. The serial data is propagated on the falling edge of

20

registers are set to their default values.

21

CS

Active Low Control Input. CS is the frame synchronization signal for the input data.

22

SCLK

Serial Clock Input. Data is captured on the positive edge of SCLK. Data can be transferred at rates of up to 50 MHz.

23

SDI

Serial Data Input. Data is captured on the positive edge of the serial clock input.

24

GPO4

General-Purpose Output 4. This pin is a digital output.

EPAD

Exposed Pad. The exposed pad is connected internally. For increased reliability of the solder joints and
