Overview
The INA215CIDCKR is a bidirectional, high-precision current sense amplifier from Texas Instruments. It features a fixed gain of 75 V/V and operates on a single supply voltage ranging from 2.7 V to 26 V. The device supports a common-mode voltage range up to 12 V and offers a gain bandwidth product of 40 kHz. Key electrical specifications include an input offset voltage of 1 µV, a CMRR of 140 dB, and a maximum operating temperature of +125 °C. It is housed in a compact SC-70-6 package.
Feature Summary
- Zero-drift architecture ensures low offset voltage for accurate sensing at small shunt voltages
- Bidirectional operation allows detection of current flow in both directions
- High common-mode rejection ratio maintains accuracy under varying common-mode conditions
Applications
- Battery management systems requiring precise current monitoring
- Overcurrent protection circuits in industrial equipment
- Load switch control applications
Procurement Notes
Verify the specific suffix 'C' indicates the commercial temperature grade (-40°C to +85°C) rather than the industrial grade ('I') when reviewing official datasheets. Confirm the SC-70-6 package marking and pinout alignment with your PCB footprint design requirements before finalizing procurement orders.
Selection Notes
Select this component when high DC accuracy is required over a wide common-mode voltage range. The fixed 75 V/V gain suits applications where the shunt voltage drop is minimal. Ensure the system's common-mode voltage does not exceed the 12 V limit specified for this variant.
Part Context
This part belongs to the INA21x family of zero-drift current sense amplifiers. These devices are designed to provide high precision by minimizing offset drift over temperature. The family includes variants with different gains and temperature grades, all sharing the same core architecture and compact packaging options.
Replacement Considerations
INA215BIDCKR: Offers industrial temperature grade instead of commercial grade.
FAQ
What is the maximum common-mode voltage supported?
The INA215CIDCKR supports a common-mode voltage range up to 12 V.
Is the output unipolar or bipolar?
The device provides a unipolar voltage output that corresponds to the bidirectional current flow through the shunt resistor.
