ANALOG CHARACTERISTICS (Continued)
Notes:
3. All outputs unloaded. All inputs CMOS level.
4. Definition for PSRR: VREFIN tied to VREFOUT, VA+ = VD+ = 5 V, a 150 mV zero-to-peak sine wave (frequency =
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 CS5466 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):
VOLTAGE REFERENCE
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
:.
6. Specified at maximum recommended output current of 1 A, source or sink.
