LMV225SD RF Detector IC Equivalent & Substitute Parts

Part Overview

The LMV225SD is an RF detector integrated circuit designed for cellular applications across the 450MHz to 2GHz frequency range. This component detects RF signals in the -30dBm to 0dBm input range with ±1dB accuracy, supporting multiple cellular standards including CDMA, CDMA2000, EDGE, GSM, GPRS, TDMA, and W-CDMA. The LMV225SD is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution of the LMV225SD is determined by strict equivalence across the following parameters:

• Frequency range: 450MHz ~ 2GHz
• RF type support: Cellular, CDMA, CDMA2000, EDGE, GSM, GPRS, TDMA, W-CDMA
• Input signal range: -30dBm ~ 0dBm
• Detection accuracy: ±1dB
• Supply voltage range: 2.7V ~ 5V
• Supply current: 8 mA
• Package configuration: 6-WDFN Exposed Pad in 6-WSON (2.2x2.5) form factor
• Mounting technology: Surface Mount

The LMV225SD/NOPB represents the direct equivalent part from Texas Instruments, maintaining identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LMV225SD/NOPB is the direct functional equivalent for applications currently using the obsolete LMV225SD. Both parts share identical electrical performance specifications and mechanical packaging, ensuring pin-for-pin and functional compatibility.

The LMV225SD/NOPB offers two significant advantages over the original part:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements, whereas the LMV225SD is RoHS non-compliant

For new designs and production transitions, the LMV225SD/NOPB is the appropriate selection. For legacy systems currently using the LMV225SD, direct substitution with LMV225SD/NOPB is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can LMV225SD/NOPB be used as a direct replacement for LMV225SD?

A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, frequency range, input signal handling, accuracy, supply requirements, and 6-WSON package configuration. No circuit redesign is required.

Q: What is the difference between LMV225SD and LMV225SD/NOPB?
