1pcs x OPA1622 DIP8 Dual Operational Amplifier Chip. It has better compatibility, lower output impedance and treble bass level, dynamic performance is very good. It perfectly solves the last shortcoming of OPA1612 and is truly a super operational amplifier.
②Input AC18V, output DC15V, current 200mA (if AC15V input is used, the load current can be larger). This board adopts double-sided solder joint design. ①The rectification part introduces the grounding concept of Marantz, which greatly reduces the ground wire interference.
