INA183A3IDBVT

Overview

The INA183A3IDBVT is a high-precision, voltage-output current-shunt monitor manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional current sensing with a common-mode voltage range extending from -200 mV to 26 V. The device features a fixed gain of 100 V/V, a gain bandwidth product of 150 kHz, and a maximum input offset voltage of 100 µV. It delivers a common-mode rejection ratio (CMRR) of 100 dB at a gain of 100 V/V. The component draws a typical operating supply current of 260 µA and functions reliably across an extended temperature range of -40°C to +125°C. It is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Provides high-precision bidirectional current monitoring with a wide common-mode voltage range supporting low-side and high-side configurations.
• Delivers stable performance with a fixed internal gain of 100 V/V and high common-mode rejection ratio for accurate shunt voltage amplification.
• Optimized for low-power applications with minimal quiescent current consumption suitable for battery-operated systems.

Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Procurement Notes

Verify the specific suffix IDBVT corresponds to the SOT-23-6 package and tape-and-reel or cut-tape availability as required. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the fixed gain configuration matches the system design requirements, as external resistor networks are not supported for this variant. Cross-reference the datasheet revision date to ensure compatibility with existing design specifications.

Selection Notes

Select the INA183A3IDBVT when a fixed gain of 100 V/V is required for precise current measurement in space-constrained designs. This component is appropriate for applications demanding low quiescent current and operation with common-mode voltages up to 26 V. Consider the SOT-23-6 package constraints for thermal management and PCB layout. Evaluate if the 150 kHz bandwidth meets the dynamic response needs of the target circuit.

Part Context

The INA183 belongs to Texas Instruments' family of high-precision current sense amplifiers designed for monitoring current flow in power delivery networks. Unlike general-purpose operational amplifiers, these devices are optimized for small differential signals superimposed on large common-mode voltages. The A3 grade indicates specific accuracy parameters regarding offset voltage and gain error compared to standard grades.

Replacement Considerations

Check for direct pin-compatible alternatives within the INA18x series, such as the INA181 or INA182, which may offer different gain options or bandwidth characteristics while maintaining the same SOT-23-6 footprint and functional interface.
