概要

Description

INA2180A1IDSGR is a Texas Instruments high-side current-sense amplifier. It measures the voltage drop across a shunt resistor in the power path and provides an output voltage proportional to the load current, enabling easy monitoring by a microcontroller ADC.
Key points:
- High-side sensing: placed between supply and load, with common-mode handling up to the supply rail.
- Single-supply operation and small 8-pin RoHS package (SGR).
- Low offset, fast response, suitable for accurate current measurement in power Management, motor control, and battery systems.
- Often offered in fixed-gain configurations with recommended shunt values.
Applications:
- Power supplies, battery management, DC-DC converters, motor drivers.
Note:
- Check the TI datasheet and product page for exact gain options, input/output ranges, bandwidth, quiescent current, pinout, and package details.

Features

Here are the typical features of the INA2180A1IDSGR (current-sense amplifier family):
- High-side current sensing: measures voltage across a shunt resistor on the supply side
- Fixed gain architecture: provides a proportional output to shunt current (no external gain resistor required)
- Wide supply range: supports single-supply operation over a broad voltage range
- Large input common-mode range: accommodates voltages up to the supply rail
- Low offset and drift: precise current measurement over temperature
- High CMRR and PSRR: robust accuracy in noisy environments
- Fast response/bandwidth: suitable for current transients
- Protection features: input protection and short-circuit/overload robustness
- Industrial temperature range: typically -40°C to 125°C
- Package: 8-pin small form factor (e.g., MSOP/SOIC) with RoHS-compliant variant (DSGR suffix)
Note: exact gain value, input ranges, and data throughput depend on the specific variant within the INA2180A1 family; consult the datasheet for precise specs.

Package

An 8-pin small-outline package (SOIC-8), RoHS/Green compliant.

Pinout

8 pins. Function: It is a high-side current-sense monitor amplifier. It measures the differential voltage across a shunt resistor (sense inputs) and outputs a voltage proportional to the sensed current. The device includes a reference pin to set the output baseline, plus power (VCC) and ground (GND) pins.
