MC33794
32
GND
Ground
This terminal and metal backing is the IC power return and thermal radiator/
conductor.
35
TEST
Test Mode Control
This terminal is normally connected to circuit ground. There are special
operating modes associated with this terminal when it is not at ground.
36–44
E1–E9
Electrode Connections
These are the electrode terminals. They are connected either directly or through
coaxial cables to the electrodes for measurements. When not selected, these
outputs are grounded through the internal resistance.
45, 46
REF_A,
REF_B
(E10, E11)
Reference Connections
(Or as additional electrodes)
These terminals can be individually selected to measure a known capacitance
value. Unlike E1-E9, these two inputs are not grounded when not selected.
47
ISO_OUT
ISO-9141 Output
This terminal translates ISO-9141 receive levels to 5.0 V logic levels for the
MCU.
51
ISO_IN
ISO-9141 Input
This terminal accepts data from the MCU to be sent over the ISO-9141
communications interface. It translates the 5.0 V logic levels from the MCU to
transmit levels on the ISO-9141 bus.
53
ISO-9141
ISO-9141 Bus
This terminal connects to the ISO-9141 bus. It provides the drive and detects
signaling on the bus and translates it from the bus level to logic levels for the
MCU.
54
LAMP_CTRL
Lamp Control
This signal is used to control the lamp driver. A high logic level turns on the lamp.
