RF Detectors Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the ordering suffix matches the required tape-and-reel configuration. Confirm RoHS compliance status aligns with current environmental regulations for your target market. Cross-reference the specific package marking code to distinguish between original National Semiconductor production and subsequent TI manufacturing runs.

RF Detectors Selection Notes

Select this component when precise logarithmic-like detection is required for wideband CDMA signals. The ±1 dB accuracy makes it suitable for closed-loop power control applications. Consider the 4-WFBGA footprint during PCB layout to ensure adequate thermal dissipation. Verify that the 2.7 V minimum supply voltage meets the system's low-power standby requirements.

RF Detectors Part Context

This part belongs to the LMV226 series, which includes variants like the LMV225 and LMV228. These detectors are engineered specifically for third-generation wireless communication protocols. The 'NOPB' suffix indicates lead-free and RoHS-compliant construction, replacing older non-compliant versions while maintaining identical electrical performance characteristics.
