概要

Description

INA216A3RSWR is TI’s high‑side current‑sense amplifier in the INA216 family. It measures the small voltage drop across a shunt resistor in series with a load and outputs a larger voltage proportional to current, suitable for an MCU/ADC.
Key points
- High‑side current sensing with a wide common‑mode range
- Low input offset and good temperature stability
- Rail‑to‑rail output for convenient ADC interfacing
- Typically offers protection features (fault/overvoltage) and a fixed gain for simple design
- Available in a Tape‑and‑Reel packaging variant (RSWR)
Applications
- Battery management, DC motor drive, power supplies, and load/current monitoring with detection/protection
How to use
- Put a shunt in series with the load, connect INA216’s inputs across the shunt, power the device from a single supply within its range, and read the output with an ADC (optionally add a reference offset).
Note
- For exact electrical specs (supply range, gain, bandwidth, CM range, offsets), consult the INA216A3RSWR datasheet on TI’s website.

Features

Here are the typical features of TI’s INA216A3RSWR (current-sense amplifier):
- High-side/current-sense amplifier for measuring across a shunt resistor
- Wide supply range (single-supply operation)
- Input common-mode range suitable for high-side sensing
- Rail-to-rail output for single-supply operation
- Low input offset voltage and low drift
- Good CMRR and PSRR to reject common-mode noise
- Short-circuit/overvoltage protection on inputs
- Low quiescent current
- RoHS-compliant small package (8-pin, tape & reel option)
Note: exact gain and some electrical specs vary by variant; consult the datasheet for precise numbers.

Package

8‑lead SOIC (SOIC‑8) package, RoHS‑compliant, Tape & Reel.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8/MSOP-8)
- Function: High-side current-sense amplifier. Differential inputs sense voltage across a shunt resistor; provides an output voltage proportional to the sensed current for ADC monitoring.
