Description
MEASOUTx output range. The MEASOUTx range defaults to the force voltage span for voltage and current
measurements, which includes some overrange to allow for offset correction. The nominal output voltage range is
±11.25 V with the default offset DAC setting, but changes for other offset DAC settings when GAIN1 = 0.
Therefore, the MEASOUTx range can be an asymmetrical bipolar voltage range. GAIN1 = 1 enables a unipolar
output voltage range, which allows the use of asymmetrical supplies or a smaller input range ADC. See Table 10
and Table 11 for more details.

Thermal shutdown feature. To disable the thermal shutdown feature, set the TMP ENABLE bit to 0 (thermal
shutdown is enabled by default).
The TMP1 and TMP0 bits allow the user to program the temperature that triggers thermal shutdown.

Configure the open-drain pin (CGALM) as a latched or unlatched output pin. When high, this bit configures the
CGALM alarm output as a latched output, allowing it to drive a controller I/O without needing to poll the line
constantly. The power-on default for this pin is unlatched.
Unused bits. Set to 0.
