Overview
The INA2180A2IDSGT is a dual-channel current-sense amplifier from Texas Instruments. It features a fixed gain of 50 V/V and operates with a supply voltage range of 2.7 V to 5.5 V. The device supports common-mode voltages up to 26 V, independent of the supply. Key electrical specifications include a maximum offset voltage of ±500 µV at 12 V common-mode, a bandwidth of 210 kHz, and a quiescent current of 500 µA. It is housed in an 8-pin WSON package.
Feature Summary
- Dual-channel architecture for simultaneous high-side or low-side current monitoring
- Integrated matched resistor network providing a fixed gain of 50 V/V
- Operates on supply voltages as low as 2.7 V while sensing common-mode signals up to 26 V
Applications
- Motor control systems
- Battery monitoring circuits
- Power management units
- Overcurrent detection protection
Procurement Notes
Verify the specific suffix IDSGT corresponds to the 8-pin WSON package variant. Confirm the A2 designation ensures the required 50 V/V gain configuration. Ensure the component meets RoHS compliance standards for your manufacturing process. Validate that the thermal characteristics of the WSON package align with your PCB layout capabilities.
Selection Notes
Select this part when dual-channel precision current sensing is required within a compact footprint. The 50 V/V gain option suits applications needing moderate amplification without external resistors. Consider the 210 kHz bandwidth for dynamic load requirements. Evaluate the 500 µA quiescent current against system power budgets.
Part Context
This component belongs to the INAx180 family of low- and high-side voltage output current-sense amplifiers. The family includes single-channel (INA180), dual-channel (INA2180), and quad-channel (INA4180) variants. All share similar electrical characteristics but differ in channel count and package options.
Replacement Considerations
Other devices in the INA2180 series such as INA2180A1IDSGT or INA2180A3IDSGT offer different gain values. Single-channel alternatives like the INA180A2DBVR provide similar performance in a smaller SOT-23 package.
