Analog ground
Interface ground
Freezes sample and hold, starts conversion with next rising edge of internal clock
Status output. If programmed as EOC, this pin is low (default) when a conversion is in progress.
If programmed as an interrupt (INT), this pin is low for a preprogrammed duration after the end
of conversion and a valid data is to be output. The polarity of EOC or INT is programmable. This
pin can also be used as a chain data input when the device is operated in chain mode.
Frame sync signal for TMS320 DSP serial interface or chip select input for SPI interface slave
select (SS-).
Non inverting input
Inverting input, usually connected to ground
No connection.
External reference input.
Connect to AGND through individual via.
Clock for serial interface
