The 44-V dual LME49860 and the 34-V single LME49710, dual LME49720, and quad LME49740 families of audio op-amps provide high linearity and a 0.00003% distortion rate. The parts offer an input noise density of 2.7 nV/√Hz, a 1/f noise corner of 60 Hz, and an output drive 600 Ω.
The LME49860 is unity-gain stable over a wide supply range of ±2.5 to 22 V and provides output current capability of 26 mA. Over this supply range, the amplifier maintains a CMRR and PSRR of more than 120 dB and a typical input bias current of 10 nA. The LME49710, LME49720 and LME49740 amplifiers are unity-gain stable over a wide supply range of ± 2.5 to 17V and provide output current capability of 45 mA. (ea/100, LME49860, $3.36; LME family, from $1.35—available now.)
