= 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):

VREFOUT REFERENCE OUTPUT VOLTAGE

Notes: 5. The voltage at VREFOUT is measured across the temperature range. From these measurements the

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