LMH6881: DC common voltage input

Jevgenij%20Kosteckij

Part Number: LMH6881

Hello,

I cannot found specification for dc common voltage input range. I use LMH6881 as single ended amplifier, one input for signal 500 mVpp and second for dc compensation (DAC +/-500 mVDC).

So what input voltage range?

Hi,

have you read section 8.1.1 of datasheet?

Hello,

As Kai has pointed out, section 8.1.1 of the datasheet delves into the input characteristics of the device. In short, the LMH6881 self biases the input common-mode of the device to 2.5V.

Best,
