概述

Description

The INA2180A3IDGKR is a Texas Instruments high‑side current‑sense amplifier. It measures the voltage across a shunt resistor and outputs a proportional analog voltage, enabling precise load-current monitoring in power supplies, motor drives, and battery-management systems. The A3 variant indicates a product grade, while DGKR denotes the package/temperature options. Typical strengths include single‑supply operation, wide common‑mode range for high‑side sensing, low offset/drift for accuracy, and fast response to current changes (no digital interface—the output is an analog voltage). Applications: motor controllers, DC‑DC converters, in‑vehicle electronics, and protection schemes. For exact electrical specs, pinout, and operating conditions, consult the TI datasheet.

Features

INA2180A3IDGKR features (concise):
- Precision instrumentation amplifier designed for current-sense and energy-meter applications.
- Wide supply range and capability to sense across low-value shunts; suitable for high-side and low-side sensing.
- High common-mode and power-supply rejection for accurate measurements in noisy environments.
- Low input offset voltage, low bias current, and low-noise performance for precise sensing.
- Programmable gain with external resistors (multiple gain options) for flexibility.
- Rail-to-rail output to maximize dynamic range on a single supply.
- Fast response/bandwidth for AC current measurement.
- Integrated protection features (overvoltage, short-circuit, ESD) and robust input protection.
- Package: 8-pin DGK, RoHS compliant; industrial temperature range (-40°C to +125°C).
Note: For exact electrical values (offset, CMRR, gain options, bandwidth, supply range), refer to the datasheet.

Package
