INA183A2IDBVT

Overview

The INA183A2IDBVT is a high-precision, voltage-output current-shunt monitor manufactured by Texas Instruments. It operates with a wide common-mode range from 2.7 V to 26 V and features a maximum offset voltage of ±170 μV, enabling accurate measurement of shunt drops as low as 10 mV full-scale. The device draws a maximum supply current of 130 µA from the IN+ pin, ensuring efficient power consumption. It has a slew rate of 0.4 V/µs and is housed in a SOT-23-5 package.

Feature Summary

• High-precision voltage-output current-shunt monitoring capability
• Wide common-mode input range supporting 2.7 V to 26 V operation
• Low offset voltage enables detection of small shunt voltage drops
• Efficient power consumption with low quiescent current draw

Applications

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

Procurement Notes

Verify the specific suffix IDBVT confirms the SOT-23-5 packaging and tape-and-reel delivery format. Confirm that the A2 grade meets the required offset voltage specifications for your application. Check part status as some listings indicate this specific variant may be obsolete; ensure availability through authorized channels before finalizing procurement plans.

Selection Notes

Select this component when precise current sensing is required within a wide common-mode voltage window. The low offset voltage makes it suitable for applications requiring accuracy at low shunt voltages. Consider the SOT-23-5 package size constraints and the 130 µA supply current impact on overall system efficiency compared to higher-power alternatives.

Part Context

The INA183 belongs to Texas Instruments' family of high-precision current sense amplifiers designed for shunt-based current monitoring. Unlike general-purpose op-amps, these devices are optimized for differential measurements near ground or high-side potentials. The INA183 specifically targets applications needing precision without the complexity of external resistor networks found in traditional instrumentation amplifier configurations.
