TEST AND DIAGNOSTIC TOOLS
V
The V
signal chain from the input of the sensor interface circuitry
(sensor amplifier) through to the output of the current mode
serial port. The function of this pin becomes active after the pin
input voltage exceeds the level of about 0.8 V. Below this level,
the ADXL180 does not respond to the voltage applied to the
V
the V
with the sensor signal.
The applied signal is zero when the input signal is equal to the
common-mode potential of the sensor interface circuitry
(~V
is typically about 640 μV/g. The scaling of the V
to the ADC code output is dependent on the range setting of
the part.

V
The V
the sensor signal chain analog output voltage at the output of
the Bessel filter. This signal is filtered and ranged as defined by
the configuration register settings. It is before the digital auto-
zero function in the signal chain. Therefore, it is not auto-
zeroed. The configuration register SCOE bit must be set to 1 to
enable this output. The signal output resistance is typically
50 Ω. Connect this output to a high impedance input only.
