Notes: 4. All outputs unloaded. All inputs CMOS level.
5. Definition for PSRR: VREFIN tied to VREFOUT, VA+ = VD+ = 3V, AGND = DGND = 0V, VA- = -2V
(using charge-pump circuit with CPD). In addition, a 106.07 mV rms (60 Hz) sinewave is imposed onto
the VA+ and VD+ pins. The “+” and “-” input pins of both input channels are shorted to VA-.
Instantaneous digital output data words are then collected for the channel under test. From these data
samples, the rms value (standard deviation) of the digital sinusoidal output signal is calculated, and this
rms value is converted into the rms 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)
