This document describes the features and characteristics of the INA105 precision single-supply differential amplifier, including gain, CMR, nonlinearity, etc.
The INA105 is a monolithic gain‑= 1 differential amplifier that integrates a precision op‑amp with laser‑trimmed metal‑film resistors for high accuracy and common‑mode rejection. It is offered in 8‑pin plastic DIP, SO‑8 surface‑mount and TO‑99 metal packages, making it suitable for a wide range of instrumentation and signal‑conditioning circuits.
The document provides electrical specifications, pin configurations, typical performance graphs, and application notes such as unity‑gain inverting, summing, and current‑receiver circuits. Package dimensions and handling warnings are also included.
