DEVICE COMMUNICATION TEST
The user can test the communication between the
Master (MCU) and the MCP3425 by simply checking
an acknowledge response from the MCP3425 after
sending a read or write command. Here is an example
a)
Set the R/W bit “LOW” in the address byte.
b)
Check the ACK pulse after sending the
address byte.
If the device acknowledges (ACK = 0), then the
device
is
connected,
otherwise
it
is
not
connected.
c)
Send a STOP bit.

DIFFERENTIAL AND SINGLE-
ENDED CONFIGURATION
Figure 6-4 shows typical connection examples for
differential and single-ended inputs. Differential input
signals are connected to the VIN+ and VIN- input pins.
For the single-ended input, the input signal is applied to
one of the input pins (typically connected to the
VIN+ pin) while the other input pin (typically VIN- pin)
is grounded. All device characteristics hold for the
single-ended configuration, but this configuration loses
one bit resolution because the input can only stand in
positive half scale. Refer to Section 1.0 “Electrical
