If The SPI interface is not used SCK (pin1), MISO (pin3), MOSI (pin4)
and CSB (pin7) must be left floating.
Self test can be activated applying logic “1” (positive supply voltage
level) to ST pins (pins 9 & 10). If ST feature is not used, then pins 9 & 10
must be left floating or connected to GND.
APPLICATION EXAMPLE
Single ended output can be formed from differential outputs by using external differential amplifier.
