INA230AIRGTT

Current Regulation/Management Overview

The INA230AIRGTT is a current sense amplifier from Texas Instruments, packaged in a 16-VQFN (3x3 mm) format. It supports high-side and low-side current monitoring with a common-mode voltage range of 0 V to 36 V. Key electrical parameters include a maximum supply voltage of 5.5 V, minimum supply voltage of 2.7 V, and operating supply current of 420 uA. The device features an input bias current of 100 pA, input offset voltage of 25 uV, and CMRR of 120 dB. Gain error is specified at 0.3%, with a gain of 1 V/V. It operates within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports both high-side and low-side current sensing configurations
• Provides digital output for current, voltage, and power monitoring
• Features high precision with low input offset voltage and bias current

Current Regulation/Management Applications

• Current monitoring in industrial automation systems

• Overcurrent protection circuits

Current Regulation/Management Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as the INA230AIRGTT may be discontinued or replaced by updated revisions such as the INA230AIRGTR. Confirm RoHS compliance and moisture sensitivity level requirements against your assembly process specifications. Ensure that the supplier provides valid traceability documentation and original manufacturer packaging to guarantee component authenticity and performance reliability.

Current Regulation/Management Selection Notes

Select this component for applications requiring precise current measurement across wide common-mode voltages up to 36 V. Consider the 16-VQFN package for space-constrained designs. Evaluate the trade-off between the 420 uA quiescent current and the required accuracy levels. Ensure the system power supply stays within the 2.7 V to 5.5 V range and that thermal conditions remain within the -40°C to +125°C operational limits for consistent performance.

Current Regulation/Management Part Context

The INA230 belongs to Texas Instruments' family of current sense amplifiers designed for digital monitoring. It integrates precision analog front-end circuitry with digital interfaces to facilitate accurate measurement of current, bus voltage, and power consumption. The AIRGTT variant denotes a specific tape-and-reel packaging option suitable for automated surface-mount assembly processes in high-volume manufacturing environments.

Current Regulation/Management Replacement Considerations

The INA230AIRGTR is listed as a manufacturer-recommended replacement for the INA230AIRGTT. Verify pinout compatibility and parameter equivalence before substitution.
