Texas Instruments INA117 High Common-Mode Voltage Difference Amplifier Datasheet
The INA117 precision difference amplifier offers a very high common‑mode input voltage range of up to +200 V while maintaining a unity‑gain error of only 0.02 % and a non‑linearity of 0.001 %. Its inputs are protected against momentary overloads of up to +500 V, making it suitable for current monitoring, battery cell‑voltage monitoring, and signal acquisition in noisy environments.
Available in 8‑pin DIP, SO‑8, and metal TO‑99 packages, the device operates from a 5 V to +18 V supply and is specified for temperatures from –55 °C to +125 °C (SM) or –40 °C to +85 °C (other packages). The datasheet includes detailed specifications, pin configuration, typical performance curves, and application circuits for current measurement and offset trimming.
