in the datasheet of the OPA180 is the Input Offset Voltage only positiv.
Typicall 15 uV and Max 75 uV. You can find it in 7.7 Electrical Charecteristic
Is there a mistake in the datsheet?
I would expect that the input offset voltage is negativ or positv.
Like Typical +-15 uV and Max +-75 uV
In all the datasheets of Ti Op Amps I have seen it the input offset voltage positiv and negativ.
Here is the Link of the datasheet: www.ti.com/.../opa180.pdf
