INA214BIDCKT

Overview

The INA214BIDCKT is a single-channel current sense amplifier from Texas Instruments, housed in an SC-70-6 surface-mount package. It operates within a supply voltage range of 2.7 V to 26 V and supports a common-mode voltage up to 12 V. Key electrical specifications include a gain bandwidth product of 30 kHz, a common-mode rejection ratio of 140 dB, and an input bias current of 28 uA. The device features a maximum input offset voltage of 1 uV and a gain error of 0.02%. It provides a fixed voltage gain of 100 V/V and draws a typical operating supply current of 100 uA. The component is rated for an extended operating temperature range from -40 C to +125 C.

Feature Summary

• Supports bidirectional current sensing with high-side or low-side output configurations
• Features zero-drift architecture for precise measurement stability
• Provides high common-mode rejection ratio for noise immunity

Applications

• Current shunt monitoring in industrial systems
• Battery management applications
• Overcurrent protection circuits

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel quantity. Ensure the selected variant matches the required temperature grade and automotive qualification status if applicable. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility and functional specifications before integration into the design.

Selection Notes

Select this component when a single-channel solution with high precision and low power consumption is required. The fixed gain of 100 V/V simplifies circuit design by eliminating external resistor networks. Consider the SC-70-6 package for space-constrained layouts. Evaluate the 12 V common-mode voltage limit against the system's bus voltage requirements to ensure proper operation within the specified range.

Part Context

This device belongs to the INA214 series of current sense amplifiers, which are designed for accurate current monitoring in various electronic systems. The series offers different gain options and package variants to suit diverse application needs. The INA214BIDCKT specifically utilizes the SC-70-6 footprint, providing a compact form factor suitable for modern printed circuit board designs requiring minimal component area.

Replacement Considerations

Check for direct substitutes within the INA214 family, such as INA214AIRSWT, noting differences in package style like UQFN-10 versus SC-70-6. Verify that alternative parts maintain compatible gain, voltage ratings, and thermal performance characteristics.
