Texas Instruments launched the OPA1662 and OPA1664 bipolar-input audio operational amplifiers. The TI op amps are ideal for USB and FireWire audio systems, analog and digital mixers, portable recording systems, and other applications that require the highest noise performance combined with low power consumption. The dual-channel OPA1662 is available now in SO-8 and MSOP-8 packages for $0.95 in 1,000-unit quantities. The quad-channel OPA1664 is available in SO-14 and TSSOP-14 packages for $1.45 (1,000-unit quantities).
The power-efficient, dual-channel OPA1662 and quad-channel OPA1664 bipolar-input audio op amps dissipate only 1.5 mA. It offers excellent noise, distortion and bandwidth performance. The TI OPA1662 and OPA1664 devices enable system designers to develop the next generation of professional and prosumer audio equipment capable of producing crisp, clean “true to the original recording” sound quality.
