It delivers a 20 MHz gain-bandwidth product and an 8.5 V/µs slew rate, which together keep harmonic distortion low across the full audio band. The rail-to-rail output stage lets it swing within millivolts of the supply rails — essential when driving an ADC input or a line output from a single 2.2 V to 5.5 V rail. Each of the two channels draws 2.15 mA supply current, making it viable for multi-channel mixers or portable audio gear where the power budget is tight. The -3dB bandwidth of 2.2 MHz confirms it will pass a 20 kHz signal with negligible roll-off, and the input bias current of 0.04 pA means it won't load high-impedance sources like electret microphones or piezo pickups. ## Active, ROHS3, no LTB risk The LME49721MA/NOPB carries an Active product status and is ROHS3 compliant. There is no last-time-buy notice or phase-out schedule on record. For new designs or production replenishment, this is a current-production part with standard lead times through independent distribution. The 8-SOIC footprint (3.90 mm body width) is a common industry standard, so board layout is straightforward.","metaTitle":"LME49721MA/NOPB Audio Op-Amp, 20 MHz GBW","metaDescription":"TI LME49721MA/NOPB dual audio op-amp: 20 MHz GBW, 8.5 V/µs slew rate, rail-to-rail output, 2.2 MHz -3dB bandwidth, 2.15 mA supply.
