• Manufacturer Part Number: AK4440
• Description: 192kHz 24-Bit 8ch DAC with 2Vrms Output
• Manufacturer: AKM [Asahi Kasei Microsystems]

(Ta = 25°C; VDD=AVDD = 4.5 ∼ 5.5V; fs = 44.1kHz; DEM = OFF; SLOW = “0”)
Note 11. The passband and stopband frequencies scale with fs(system sampling rate). For example, PB=0.4535×fs
Note 12. The calculating delay time which occurred by digital filtering. This time is from setting the 16/24bit data of
(Ta = 25°C; VDD=AVDD = 4.5~5.5V; fs = 44.1kHz; DEM = OFF; SLOW = “1”)
Note 13. The passband and stopband frequencies scale with fs. For example, PB = 0.185×fs (@±0.04dB), SB =
(Ta = 25°C; VDD=AVDD = 4.5 ∼ 5.5V)
Note 14. The current of the P/S pin is not included. The P/S pin has an internal pull-up resistor (typ.100kΩ).
