INA215AIDCKR

Overview

The INA215AIDCKR is a single-channel current sense amplifier from Texas Instruments, packaged in a SC-70-6 surface-mount case. It operates on a supply voltage ranging from 2.7 V to 26 V with a quiescent current of 100 uA. The device features a fixed gain of 75 V/V and supports bidirectional measurements via high-side or low-side configurations. Key electrical specifications include a maximum common-mode voltage of 12 V, a gain bandwidth product of 40 kHz, and an input offset voltage of 1 uV. It maintains a common-mode rejection ratio of 140 dB and functions within a temperature range of -40 C to +125 C.

Feature Summary

• Provides high precision current monitoring with ultra-low input offset voltage for accurate signal detection.
• Supports both high-side and low-side measurement topologies for flexible circuit integration.
• Delivers exceptional common-mode rejection to maintain accuracy in noisy environments.

Applications

• Battery management systems requiring precise current tracking
• Industrial process control loops with shunt-based sensing
• Overcurrent protection circuits in power distribution units

Procurement Notes

Verify the specific suffix IDCKR against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required gain and operating temperature range for your specific application environment before finalizing procurement orders.

Selection Notes

Select this component when high accuracy is critical due to its microvolt-level offset voltage. The wide common-mode voltage range allows use in various power rail configurations. Consider the fixed gain of 75 V/V to ensure the output swing aligns with your ADC input requirements without additional amplification stages.

Part Context

This part belongs to the INA215 series of current sense amplifiers designed for general-purpose monitoring applications. It shares the SC-70-6 footprint with other devices in the family but differs in gain and bandwidth characteristics. The series focuses on providing robust performance in space-constrained designs while maintaining high linearity.

Replacement Considerations

Check the INA215AIDCKT for tape-and-reel packaging alternatives. Verify functional equivalence with INA215 variants having different gain settings if system headroom allows adjustment.
