HOW TO CHOOSE THE OPM401(or OPM402) AND OPM2401(or OPM2402)

OPM401(or OPM402) and OPM2401(or OPM2402) are selected according to an opamp circuit impedance values.

1. OPM401(or OPM402): Use for the low impedance circuit

    Feedback-Resistor is less than 1000 ohm

    Headphone-Amp output circuit (only if the supply voltage is ± 5V or less)

    However, due to high Supply Current (Quiescent Current), depending on the product, you need to check it even if the Supply Voltage is reduced.

2. OPM2401(or OPM2402): Use for a high impedance circuit

    Feedback-Resistor is more than 1000 ohm

    However, the Supply Current (Quiescent Current) is low.

3. If you do not know the value of the Feedback-Resistor or uncertain, the two, it is recommended that you choose to try the actual use.

Feedback Resistor is:

Resistor connected between the Negative Input and Out in opamp circuit.

Use this product under the following conditions:

  In OPAMP circuit, "the final gain" is equal to or less than the x10 (+ 20dB). (Active filter, buffer, etc.)

  The length of the Extension DIP8 should be as short as possible.
