JAJSJ91A June 2020 – June 2021 INA237-Q1
PRODUCTION DATA
The first step to program the INA237-Q1 is to properly set the device and ADC configuration registers. On initial power up the CONFIG and ADC_CONFIG registers are set to the reset values as shown in Table 7-5 and Table 7-6. In this default power on state the device is set to measured on the ±163.84 mV range with the ADC continuously converting the shunt voltage, bus voltage, and temperature. If the default power up conditions do not meet the design requirements, these registers will need to be set properly after each VS power cycle event.
