Note 7. PSR is applied to AVDD1, AVDD2, DVDD, TVDD1 and TVDD2 with 1kHz, 50mVpp. VREFH1 and VREFH2
pins are held a constant voltage +3.3V.
Note 8. This value is (LIN+) – (LIN-) and (RIN+) – (RIN-). The voltage is proportional to VREFH1, VREFH2 voltage.
Note 9. VREFH1 and VREFH2 are held +3.3V, the input bias voltage is set to AVDD1, 2 x 0.5. The 1kHz, 0.96Vpp
signal is applied to LIN- and LIN+ with same phase (e.g. shorted) or RIN- and RIN+. The CMRR is measured as
the attenuation level from 0dB = -7dBFS (since the normal 0.96Vpp = -7dBFS). This value is guaranteed but not
tested.
Note 10. For AC-load. In the case of DC-load is 5kΩ.
Note 11. This value is Load Capacitance for output pin to GND. In differential mode, this value should be estimated to be
twice, because Load Capacitance exists to GND and between the differential pin.
