Overview
The INA2180A1IDSGT is a dual-channel current-sense amplifier from Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and supports common-mode voltages up to 26 V. The device features a fixed gain of 20 V/V, a bandwidth of 350 kHz, and an output slew rate of 2 V/µs. Maximum offset voltage is ±150 µV at zero common-mode voltage and ±500 µV at 12 V common-mode voltage. Quiescent current is typically 355 µA with a maximum of 500 µA. It is housed in an 8-pin WSON package.
Feature Summary
- Supports high-side and low-side sensing with common-mode input range extending from -0.2 V to +26 V
- Integrates a matched resistor network for precise gain accuracy and reduced temperature drift
- Provides high bandwidth and fast slew rate for rapid detection of current changes
Applications
- Motor control systems
- Battery monitoring circuits
- Power management units
- Overcurrent detection protection
- Solar inverter applications
Procurement Notes
Verify the specific suffix IDSGT corresponds to the 8-pin WSON package variant. Confirm the A1 designation indicates the 20 V/V gain option. Ensure the component meets RoHS compliance requirements for your assembly process. Check the datasheet for absolute maximum ratings to prevent damage during operation.
Selection Notes
Select this part when dual-channel current monitoring is required within a 26 V common-mode environment. The 20 V/V gain suits applications requiring moderate amplification of shunt voltages. Consider the 350 kHz bandwidth for dynamic load responses. Evaluate thermal performance based on the WSON package characteristics and ambient operating conditions.
Part Context
This component belongs to the INAx180 family of cost-optimized current-sense amplifiers. The family includes single-channel (INA180), dual-channel (INA2180), and quad-channel (INA4180) variants. All devices share similar electrical characteristics but differ in channel count and package options such as SOT-23, VSSOP, TSSOP, and WSON.
Replacement Considerations
Other members of the INAx180 family may serve as alternatives depending on channel requirements. Single-channel equivalents include the INA180 series. Quad-channel options are available via the INA4180 series. Verify pin compatibility and package dimensions before substituting.
