概述
Description
INA216A3RSWR is a Texas Instruments instrumentation amplifier (INA216 family) used to amplify small differential signals with high common-mode rejection. It’s designed for precision sensing in single‑supply systems, such as shunt current sensing, bridge sensors, and other low-level signal interfaces in battery-powered or industrial electronics. The “A3” is a performance grade, while “RSWR” denotes the 8‑pin package with tape-and-reel packaging. Typical strengths include low input offset and drift, low bias current, and good CMRR, with rail-to-rail input/output on a suitable supply range. Gain is set externally (per the datasheet) for differential amplification in various configurations. For exact specs—gain options, input offset voltage, noise, CMRR, power supply range, and PSRR—see the INA216A3RSWR datasheet.

Pinout
- Pin count: 8 pins (RSWR package, 8-pin device).
- Function: Single-channel instrumentation amplifier. It takes a differential input (IN+ and IN−), provides a single-ended output, and uses a gain-setting pin (RG) and a reference pin (REF) to set the gain and output level. Includes power supply pins (V+ and V−). Commonly used to amplify small voltages across a shunt resistor for precise current sensing.
