Working Principles

The TLV2170IDR is based on a voltage feedback architecture. It utilizes a differential input stage followed by a gain stage and an output buffer. The differential input stage amplifies the voltage difference between the IN+ and IN- pins. The amplified signal then goes through the gain stage, which further amplifies the signal based on the desired gain configuration. Finally, the output buffer provides a low impedance output that can drive external loads.
