Texas – Latest op amps set new performance and power benchmarks for audio systems (OPA1662)
Oct 26 2012 - Design & Manufacture [More Design & Manufacture Articles]Two new bipolar-input audio operational amplifiers (op amps) have been unveiled by Texas Instruments (TI) offering unmatched noise, distortion and bandwidth performance while dissipating a mere 1.5mA.
The power-efficient, dual-channel OPA1662 and quad-channel OPA1664 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. The op amps are targeted at 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 in SO-8 and MSOP-8 packages. The quad-channel OPA1664 is available in SO-14 and TSSOP-14 packages
The OPAMPEVM universal op amp evaluation module (EVM) is available to accelerate the development of audio equipment using the OPA1662 and OPA1664. The Active Filter Designer tool can help system designers implement an op amp filter design. TINA-TI SPICE models and reference designs are also available for the OPA1662 and OPA1664 op amps, says the company.
