5. Definition for PSRR: VREFIN tied to VREFOUT, VA+ = VD+ = 3V, AGND = DGND = 0V, VA- = -2V
7. For OWRS and GAIN pins, input leakage current is 30 µA (Max).
(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-. 2048
instantaneous digital output data words are collected for the channel under test. The rms value 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):
