voltage at VA+ and VD+ pins. The “+” and “-” input pins of both input channels are shorted to VA-. Then the CS5461 is commanded to continuous

conversion acquisition mode, and digital output data is collected for the channel under test. The (zero-to-peak) value of the digital sinusoidal output

signal is determined, and this value is converted into the (zero-to-peak) value of the sinusoidal voltage (measured in mV) that would need to be

7. When voltage level on PFMON is sagging, and LSD bit is at 0, the voltage at which LSD bit is set to 1.

8. If the LSD bit has been set to 1 (because PFMON voltage fell below PMLO), this is the voltage level on

PFMON at which the LSD bit can be permanently reset back to 0.

Notes: 9. The voltage at VREFOUT is measured across the temperature range. From these measurements the

following formula is used to calculate the VREFOUT Temperature Coefficient:.
