OPA2376: output capacitive load

Ryuuichi machida

Part Number: OPA2376

Hi,

Let me confirm about below.

* According to datasheet, there is following description.

"The OPAx376 in a unity-gain configuration can directly drive up to 250pF of pure capacitive load."

Is there any restriction of input/output signal in above condition ?

Especailly, what I would like you to confirm are

1. Is there any restriction for "output current" ?

2. Is there any restriction for "frequency of input signal" ?

Best regards,

Machida

    Hello Machida,

    1. Is there any restriction for "output current" ?

    Yes, the short circuit current for this device is +30mA, -50mA.

    2. Is there any restriction for "frequency of input signal" ?

    The restrictions with be determined by bandwidth (GBW:5.5MHz). Another restriction to be aware of is maximum output vs Frequency (page12 of datasheet) shown below:
