Part Number: MSP430FR2355
Dear MSP430 team,
12-bit DAC of Smart Analog Combo uses internal shared reference Vref for its operation.
Is it advisable to use a certain TLV Vref calibration value in order to increase accuracy?
DACcodeCalibrated = DACcode *2 *VrefCalibrationValue /0x10000
Hi Marek,
This method is advisable. The TLV data of chip includes 1.5V reference calibration data. And if you want, you can use the internal reference as ADC reference and measure a high accuracy external voltage to get the calibration data. Then store the data into TLV memory. Please see the user's guide and datasheet for more details.
