Note 8. The voltage on (VREFH − VREFL) is held +5V externally.
Note 9. Full-scale voltage(0dB). Output voltage scales with the voltage of (VREFH − VREFL).
Note 10. For AC-load. 1.5kΩ for DC-Load
Note 11. typ. 5mA (@ DVDD=3.3V, fs ≤ 96kHz), typ. 8mA (@ DVDD=3.3V, fs = 192kHz)
Note 12. In the power-down mode. P/S pin = TTL pin = DVDD, and all other digital input pins including clock pins
Note 13. PSR is applied to AVDD, DVDD with 1kHz, 100mVpp. VREFH pin is held +5V.
MS0336-E-00
AOUT (typ.@0dB) = (AOUT+) − (AOUT−) = ±2.8Vpp × (VREFH − VREFL)/5.
(MCLK, BICK and LRCK) are held DVSS.
