SSM2275中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The SSM2275 and SSM2475 use the Butler Amplifier front end, which combines both bipolar and FET transistors to offer the accuracy and low noise performance of bipolar transistors and the slew rates and sound quality of FETs. This product family includes dual and quad rail-to-rail output audio amplifiers that achieve lower production costs than the industry standard OP275 (the first Butler Amplifier offered by Analog Devices). This lower cost amplifier also offers operation from a single 5 V supply, in addition to conventional ±15 V supplies. The ac performance meets the needs of the most demanding audio applications, with 8 MHz bandwidth, 12 V/µs slew rate and extremely low distortion.
