4. All outputs unloaded. All inputs CMOS level.
5. Measurement method for PSRR: VREFIN tied to VREFOUT, VA+ = VD+ = 5 V, a 150 mV
6. When the voltage level on PFMON is sagging and LSD bit = 0, this is the voltage at which LSD is set to 1.
7. If the LSD bit has been set to 1 (because PFMON voltage fell below PMLO), this is the voltage level on
(zero-to-peak) (60 Hz) sinewave is imposed onto the +5 V DC supply voltage at VA+ and VD+ pins. The
“+” and “-” input pins of both input channels are shorted to AGND. The CS5467 is then 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 applied
at the channel’s inputs, in order to cause the same digital sinusoidal output. This voltage is then defined
as Veq. PSRR is (in dB)
PFMON at which the LSD bit can be permanently reset back to 0.
