DEVICE CONNECTION TEST
The user can test the presence of the MCP3426/7/8 on
the I2C bus line without performing an input data
conversion. This test can be achieved by checking an
acknowledge response from the MCP3426/7/8 after
sending a read or write command. Here is an example
a.
Set the R/W bit “HIGH” 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 STOP or START bit.

DIFFERENTIAL AND
SINGLE-ENDED CONFIGURATION
Figure 6-4 shows typical connection examples for
differential and single-ended inputs. Differential input
signals can be connected to the CHn+ and CHn- input
pins, where n = the channel number (1, 2, 3, or 4). For
the single-ended input, the input signal is applied to one
of the input pins (typically connected to the CHn+ pin)
while the other input pin (typically CHn- 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
