Technical Data

Distributed System Interface

(DSI) Sensor Interface

33793/A

The 33793 is a slave Distributed System Interface (DSI) device

that is optimized as a sensor interface. The device contains circuits

to power sensors such as accelerometers and to digitize the analog

level from the sensor. The device is controlled by commands over the

DSI bus and returns measured data over the bus.

DISTRIBUTED SYSTEM INTERFACE
