This command returns the most recent ADC measured value of the voltage measured at the V
IN_SNS
pin.
READ_VIN Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Read_vin[15:0] The data uses the L11 format.
Units: V
READ_VOUT
This command returns the most recent ADC measured value of the channel’s output voltage. When odd channels are
This command returns the most recent ADC measured value of the channel’s output voltage. When odd channels are
configured to measure current, the data contents use the L11 format with units in mV.
READ_VOUT Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Read_vout[15:0] The data uses the L16 format.
Units: V
READ_VOUT Data Contents—for Odd Channels Configured to Measure Current (Mfr_config_adc_hires = 1)
Bit(s) Symbol
Operation
b[15:0] Read_vout[15:0] The data uses the L11 format.
Units: mV
READ_TEMPERATURE_1
