Overview
The INA293A2IDBVR is a unidirectional current sense amplifier from Texas Instruments, designed for high-voltage applications with a common-mode voltage range of -4 V to 110 V. It features a fixed gain of 50 V/V and operates on a single supply voltage between 2.7 V and 20 V. The device offers a bandwidth of 900 kHz, an input offset voltage of 15 µV, and a maximum gain error of 0.02%. It functions within a temperature range of -40°C to +125°C and is housed in a compact SOT-23-5 package.
Feature Summary
- Supports high common-mode voltages up to 110 V for flexible system integration
- Provides ultra-precise measurement capabilities with low offset voltage and minimal gain error
- Delivers high bandwidth performance suitable for fast transient detection
Applications
- Industrial motor control systems
- Power supply current monitoring
- Battery management systems
Procurement Notes
Verify the specific suffix IDBVR corresponds to the SOT-23-5 tape-and-reel packaging configuration. Confirm that the A2 variant matches the required 50 V/V gain setting for your circuit design. Ensure compatibility with the specified -4 V to 110 V common-mode voltage range before procurement.
Selection Notes
Select this component when high-side current sensing is required in environments with large common-mode voltages. The fixed 50 V/V gain is optimal for translating small shunt voltages into measurable output levels without external resistor networks. Consider the 900 kHz bandwidth for applications requiring rapid response to load changes.
Part Context
This device belongs to the INA293 family of high-precision current sense amplifiers. It shares architectural similarities with other members like the INA293A4 and INA293B5 but differs in its specific gain setting and precision class. The family is characterized by zero-drift technology and robust high-voltage operation capabilities.
Replacement Considerations
INA293A4IDBVR provides a 200 V/V gain option within the same package. INA293B5IDBVR offers a 500 V/V gain variant. For automotive applications, consider the INA293A2QDBVRQ1 which meets AEC-Q100 standards.
