Hello.

I attached the new op amp schematic opm320-v1_06-12pcs-2024119-circuit.pdf schematic to you before, and here is the explanation of some changes.

 

  1. Some changes have been made.
  2. it is produced with this final change so far.

 

The new opamp schematic opm320-v1_06-12pcs-2024119-circuit.pdf schematic had final changes as we produced it.

The reasons for the changes are as follows:

1-1. To reduce the power quiescent current, we increased R7 from 75R0 to 100R0 to reduce the reference current.

As a result, the power standby current is about 7mA~12mA in total.

1-2. c3 and c6 were removed from 27pF to 0pF to increase the rolloff frequency of the high frequency band.

That's all the changes. In this state, 1 channel is produced by soldering individual parts to a small PCB, and the single-type product is produced by placing one circuit, and the dual-type product is produced by placing two circuits.

continue.
