1. Applies when the HPF option is enabled.
2. Applies before system calibration.
3. All outputs unloaded. All inputs CMOS level.
4. Measurement method for PSRR: VREFIN tied to VREFOUT, VA+ = VD+ = 5 V, a 150 mV (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. Then the CS5461A 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 applied at the channel’s inputs, in order to cause the same digital sinusoidal output.
This voltage is then defined as Veq. PSRR is then (in dB) :
? 150 ?
? V eq ?
5. When voltage level on PFMON is sagging, and LSD bit is at 0, the voltage at which LSD bit is set to 1.
6. 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.
