Audio op-amp with headphone-grade output drive
The Texas Instruments LME49726MY/NOPB is a dual audio operational amplifier from the LME® series, with two rail-to-rail output stages in an 8-HVSSOP package. It delivers a 6.25 MHz gain-bandwidth product and a 3.7 V/µs slew rate.
350 mA output — what it means for the audio chain
The LME49726MY/NOPB's 350 mA output per channel can drive headphones directly, saving board area and BOM cost. The exposed pad on the 8-HVSSOP package requires a solid thermal via array to the ground plane.
Supply and temperature range — field-fit check
The part runs on 2.5 V to 5.5 V total supply, single or split. The -40°C to 85°C temperature range covers outdoor telecom cabinets, automotive cabin audio, and factory-floor public-address systems.
Active lifecycle — no LTB pressure on the BOM
TI lists the LME49726MY/NOPB as Active with ROHS3 compliance. No NRND flag, no last-time-buy notice as of the current record. The part is sourced through independent distribution and quoted to order against an RFQ.
