= 60 Hz) is imposed onto the +5 V supply voltage at VA+ and VD+ pins. The “+” and “-” input pins of both input
channels are shorted to VA-. Then the CS5462 is put into an internal test mode and digital output data is collected
for the channel under test. The zero-peak value of the digital sinusoidal output signal is determined, and this value
is converted into the zero-peak value of the sinusoidal voltage 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):
following formula is used to calculate the VREFOUT Temperature Coefficient:.
Definition for PSRR: VREFIN tied to VREFOUT, VA+ = VD+ = 5 V, a 150 mV zero-to-peak sine wave (frequency
