ANALOG CHARACTERISTICS (Continued)
Notes: 3. The minimum FSCR is limited by the maximum allowed gain register value.
4. All outputs unloaded. All inputs CMOS level.
5. Definition 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 CS5550 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):
VOLTAGE REFERENCE
Notes: 6. The voltage at VREFOUT is measured across the temperature range. From these measurements the
following formula is used to calculate the VREFOUT Temperature Coefficient:.
