• Manufacturer Part Number: AK5371AVQ
• Description: 2ch A/D Converter with USB I/F
• Manufacturer: AKM [Asahi Kasei Microsystems]

MS0546-E-00
The following figure shows the system connection diagram. This is an example which uses external 1K bit EEPROM (AK93C45A)
as Device and String Descriptor. If EEPROM is not used, EPEN pin should be tied to VSS1.
Ceramic capacitors (0.1uF) for VA pin, VD pin, VREF pin and VCOM pin should be located as near as possible.

C1 is specified for lower end cut-off frequency
C3 forms Anti-aliasing filter in conjuction with the internal resistor at AMPR2O/AMPL2O
R0: 0Ω resister when BIASSEL is Low. 330Ω resister when BIASSEL is High
Cd: Please select the appropriate value according to crystal resonator’s characteristics
