TLV172: Pin layout missing in the datasheet

Mykhailo Borysov

Part Number: TLV172
Other Parts Discussed in Thread: OPA172, OPA197

There is no pin layout for TLV172 in the datasheet. This chip uses SOT-23-5 or SC70-5 package, which is atypical for opamps. Therefore I can't rely on a "standard" opamp pin layout and proceed with my design. Can anyone help?

Hi Mykhailo,

Thanks for bringing this to our attention, we'll get this added to the datasheet. Please use the pin layout shown in the OPA172 datasheet, they will be the same as the TLV172.

Sincerely,
Paul

From previous version of data sheet.

What is the difference OPA172/TLV172/OPA197? Can I use OPA172 and OPA197 as an alternate to TLV172?

It seems that OPA172 is an improved version of the TLV172. Whereas most of the specs are the same (such as operating conditions), most of the parameters are slightly better. This includes the input offset voltage, its temperature drift, voltage noise spectral density and so on.

But OPA172 is somewhat more expensive, too.

Mykhailo, you are correct. The OPA172 is a similar device to the TLV172 but has better parameters and more values which are given as maximum allowed. This does raise the cost.
