• Manufacturer Part Number: AK4340_06
• Description: 192kHz 24-Bit Stereo ?? DAC with 2Vrms Output
• Manufacturer: AKM [Asahi Kasei Microsystems]

ASAHI KASEI
Data is shifted in via the SDTI pin using BICK and LRCK inputs. In serial control mode, five serial data mode can be
selected by DIF2-0 bits. (See Table 5). In parallel control mode, two serial data mode can be selected by DIF0 pin. (See
Table 6) In all modes the serial data is MSB-first, 2’s compliment format and is latched on the rising edge of BICK. Mode
2 can be used for 16/20 MSB justified formats by zeroing the unused LSBs.
