Note 7. By
Note 8. The voltage on (VREFHL/R − VREFLL/R) is held +5V externally.
Note 9. Full-scale voltage(0dB). Output voltage scales with the voltage of (VREFHL/R − VREFLL/R).
Note 10. For AC-load. 1.5kΩ for DC-Load
Note 11. In the power-down mode. PSN pin = DVDD, and all other digital input pins including clock pins
Note 12. PSR is applied to AVDD, DVDD with 1kHz, 100mVpp. The VREFHL/R pin is held +5V.
MS1046-E-00
AOUT (typ.@0dB) = (AOUT+) − (AOUT−) = ±2.8Vpp × (VREFHL/R − VREFLL/R)/5.
(MCLK, BICK and LRCK) are held VSS4.
