Part Number: TLV9052

Hi team,

Is there any problem if SHTDpin is OPEN for TLV9052S?

Sincerely.
Kengo.

    Section 8.3.9 of the datasheet says:

    To ensure optimal shutdown behavior, the SHDN pins should be driven with valid logic signals. […] The shutdown pin circuitry includes a pull-up resistor, which will inherently pull the voltage of the pin to the positive supply rail if not driven. Thus, to enable the amplifier, the SHDN pins should either be left floating or driven to a valid logic high. To disable the amplifier, the SHDN pins must be driven to a valid logic low .While we highly recommend that the shutdown pin be connected to a valid high or a low voltage or driven, we have included a pull-up resistor connected to VCC.
