Overview
The INA241B5IDR is a bidirectional current sense amplifier from the Texas Instruments INA241B series, housed in an SOIC-8 package. It features a fixed gain of 200 V/V and operates with a common-mode voltage range of -5V to 110V. The device supports a supply voltage between 2.7V and 20V, drawing a typical quiescent current of 2.5mA. Key electrical specifications include a maximum gain error of ±0.1%, a maximum input offset voltage of ±150µV, and a DC common-mode rejection ratio (CMRR) of 120dB. It provides a small-signal bandwidth of 1.1MHz and a slew rate of 8V/µs.
Feature Summary
- Enhanced PWM rejection circuitry minimizes output signal disturbances caused by high-speed common-mode voltage transients at the inputs.
- Bidirectional operation enables accurate measurement of voltage drops across shunt resistors regardless of current direction.
- Wide common-mode voltage range allows for high-side, low-side, and inline sensing applications independent of the supply voltage.
Applications
- Motor drives
- Solenoids and actuators
- Cordless power tools
Procurement Notes
Verify the specific suffix ID indicates the SOIC-8 package variant when sourcing. Confirm that the B-series accuracy specifications meet the system requirements for gain error and offset voltage. Ensure the operating temperature range aligns with the intended industrial or automotive environment constraints.
Selection Notes
Select this component when a high fixed gain of 200 V/V is required to amplify small differential signals from low-value shunt resistors. The B-series offers higher gain error compared to the A-series but maintains robust performance for general-purpose precision sensing. Consider the SOIC-8 package for standard surface-mount assembly processes.
Part Context
This device belongs to the INA241x family of ultra-precise current sense amplifiers designed for high-voltage switching systems. The family includes multiple gain options and accuracy grades (A and B series). The INA241B5IDR specifically targets applications requiring high gain and moderate precision within a wide common-mode voltage window.
Replacement Considerations
INA241B5IDRG4 is a lead-free version of the same functional device. Other gain variants within the INA241B series share identical pinouts and core functionality but differ in amplification factors.
