Advance Information

DSI 2.02 Sensor Interface

33784

The 33784 is a slave, Distributed System Interface Bus (DBUS),

version 2.02 compatible device, 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 bus, and returns measured data

and other information over the bus.

SENSOR INTERFACE

Features

• DSI version 2.02 compatible

• 2-channel, 10-bit analog-to-digital converter (ADC)

• 3 pins configurable as logic inputs or outputs

• Provides regulated +5.0v output for sensor power from bus

• On-board clock (no external elements required)

• Includes bus switches on bus and bus return

• Pb-free packaging designated by suffix code EF
