Procurement Notes

Verify the specific suffix IDBVT indicates the SOT-23-5 package and reel/cut-tape availability. Confirm the A2 grade corresponds to the 50 V/V fixed gain setting. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Check RoHS compliance status as specified in the official datasheet. Validate pinout alignment with the target PCB footprint before integration.

Selection Notes

Select this component when a fixed gain of 50 V/V is required for current sensing applications. It is suitable for designs needing operation with common-mode voltages up to 26 V. Consider this part for space-constrained layouts due to its compact SOT-23-5 packaging. Evaluate the 260 µA supply current against system power budgets. Ensure the 8 mA output drive capability meets load requirements.
