Pin provides a regulated 5.0V output. The power is derived from the bus.
This pin must be grounded in the application.
Pins can be used to provide a logic level output or a logic input.
Inputs to the ADC.
Pin is the low reference level and power return for the analog-to-digital
converter (ADC). It is internally connected to RTNIN.
This pin must be grounded in the application.
Input pin for measuring device quiescent current. Must be left open in the
application.
This pin must be grounded in the application.
Switched RTNIN pin, attaches to the next RTNIN pin in the daisy chain.
Pin attaches to the low side of the differential bus, and provides the common
return for power and signalling. It is internally connected to AGND.
Switched BUSIN Pin, attaches to the next BUSIN pin in the daisy chain.
Pin attaches to the high side of the differential bus and responds to
initialization commands.
A capacitor attached to this pin is charged by the bus during bus idle and
supplies current to run the device and for external devices via the REGOUT
pin during non-idle periods.
