INA183A1IDBVR

Overview

The INA183A1IDBVR is a precision current sense amplifier manufactured by Texas Instruments. It operates with a supply voltage range of 2.7 V to 26 V and supports bidirectional current sensing. The device features a fixed gain of 50 V/V, ensuring high accuracy with a maximum gain error of 0.1%. It provides a common-mode voltage range from -0.1 V to +26 V and includes an internal reference output. Key electrical specifications include a bandwidth of 400 kHz, a slew rate of 0.3 V/µs, and an input offset voltage of 25 µV. The component is housed in a five-pin SOT-23 package.

Feature Summary

• Bidirectional current sensing capability for accurate measurement in both directions
• High precision performance with low gain error and low input offset voltage
• Wide common-mode voltage range extending below ground potential
• Integrated internal reference output for simplified system design

Applications

• Battery management systems
• Industrial process control
• Power supply monitoring

Procurement Notes

Verify the specific grade suffix 'A1' to ensure the required gain error tolerance of 0.1% is met. Confirm the DBV package variant matches the PCB footprint requirements. Check RoHS compliance status against project specifications. Ensure the operating temperature range covers the intended environmental conditions. Validate pinout compatibility during integration planning.

Selection Notes

Select this component when bidirectional sensing is required within a 26 V common-mode limit. The fixed 50 V/V gain suits applications needing high resolution without external resistors. Consider the SOT-23 package size for space-constrained designs. Evaluate the 400 kHz bandwidth against signal frequency requirements. Compare power consumption and noise density with alternative amplifiers if low-power operation is critical.

Part Context

This part belongs to the INA183 family of precision current sense amplifiers. It shares the same core architecture as other variants but differs in gain and accuracy grades. The family is designed for general-purpose current monitoring in industrial and consumer electronics. Other members may offer different gains or packaging options while maintaining similar electrical characteristics.

Replacement Considerations

Direct substitutes include other INA183 variants with compatible gain and package types. Verify that any replacement maintains the bidirectional sensing feature and similar common-mode voltage range. Ensure the substitute meets the same thermal and electrical specifications for seamless integration.
