The LME49713MAX is a high-performance, ultra-low distortion Current Feedback (CFB) operational amplifier specifically designed for high-fidelity audio applications. Mouser

Product Overview

The LME49713MAX (SOIC-8 package) is renowned for its extreme speed and signal fidelity, characterized by a slew rate of 1900 V/µs and a Total Harmonic Distortion (THD+N) of just 0.00036%. Mouser Digikey

Key Technical Specifications: Mouser

Architecture: Current Feedback (CFB)
Bandwidth: 132 MHz
Input Noise: 1.9 nV/√Hz
Output Current: ±100 mA
Supply Range: ±5V to ±18V

Market Trends & Status

Lifecycle Status: Obsolete / Discontinued. Mouser The product is no longer recommended for new designs (NRND). Original manufacturer Texas Instruments has largely transitioned this product line to End-of-Life (EOL).
Supply Scarcity: As a discontinued "fever-grade" audio chip, authentic stock is increasingly rare on mainstream distributor sites like DigiKey and Mouser. Digikey Most remaining inventory is held by specialized B2B electronic component distributors, primarily in hubs like Shenzhen, China.
Pricing Trend: Due to its "cult" status in the audiophile community and limited supply, prices on the secondary market can fluctuate significantly, often selling at a premium compared to its original MSRP.

Strategic Sourcing Insights

For designers or repair technicians, direct replacements are challenging due to its unique Current Feedback architecture.

Direct Family Alternatives: The LME49720MA (Dual) or LME49710 (Single) are common Voltage Feedback alternatives from the same family, though they do not match the 1900V/µs slew rate of the LME49713. Ti Chipdip
Market Alternatives: The LM6172 is a notable high-speed CFB alternative currently available from verified B2B suppliers. Alibaba
