ak4373 ETC-unknow, ak4373 Datasheet - Page 85

• Manufacturer Part Number: ak4373
• Description: Low Power Stereo Dac With Hp/spk-amp
• Manufacturer: ETC-unknow

MS0991-E-00
Power Supply
2 .2 ∼ 3.6V
Notes:
Mono In
- VSS1, VSS2 and VSS3 of the AK4373 must be distributed separately from the ground of external controllers.
- All digital input pins must not be left floating.
- When the AK4373 is EXT mode (PMPLL bit = “0”), a resistor and a capacitor of the VCOC pin are not needed.
- When the AK4373 is PLL mode (PMPLL bit = “1”), a resistor and a capacitor of the VCOC pin are shown in
- When the AK4373 is used at master mode, LRCK and BICK pins are floating before M/S bit is changed to “1”.
- If the Analog Mixing block will is used as a single-ended, the MIN- pin must be connected to VSS1 in series
Table
Therefore, 100kΩ around pull-up resistor must be connected to LRCK and BICK pins of the AK4373.
with a capacitor to avoid induced external noise.
