High performance audio amps for a range of applications
28 August 2002, Analogue, Mixed Signal, LSI

A world leader in amplifiers, Analog Devices (ADI) offers a range of audio amplifiers for many audio applications.

ADI set the industry standard with its OP275 dual bipolar/JFET op-amp for pro audio. OP275 was the first amplifier that featured the Butler Amplifier front end that combined both bipolar and JFET transistors to attain the accuracy and low-noise performance of bipolar transistors, as well as the speed and sound quality of JFETS.

Building on that legacy ADI developed the SSM2275 and SSM2475 rail-to-rail output audio amplifiers. Dual and quad, respectively, both use the Butler Amplifier front end. They feature single or dual-supply operation, and their AC performance meets the needs of the most demanding audio applications.

For high-performance portable or low-power audio systems, ADI offers the SSM2135 dual audio op-amp. This device has an operating supply range of 4-36 V or 2-18 V, as well as low distortion and excellent sonic characteristics.

For applications with a mono internal speaker and stereo headphones, the company recommend using the SSM2250. An ideal audio solution, the SSM2250 can simplify design and lower costs since it requires a minimum of external components.
