General Description

OUT A 1 –IN A +IN A V– 2 3 4 Rail-to-Rail Output Audio Amplifiers SSM2275/SSM2475* PIN CONFIGURATIONS 8-Lead Narrow Body SOIC (SO-8) 8 V+ 14-Lead Narrow Body SOIC (R-14) OUT A 1 –IN A 2 +IN A 3 V+ 4 +IN B 5 –IN B 6 OUT B 7 14 OUT D 13 –IN D 12 +IN D SSM2275 (Not to Scale) 7 6 5 OUT B –IN B +IN B SSM2475 (Not to Scale) 11 V– 10 +IN C 9 8 –IN C OUT C 8-Lead microSOIC (RM-8) OUT A –IN A +IN A V– 1 8 V+ OUT B –IN B +IN B OUT A –IN A +IN A V+ +IN B –IN B OUT B 14-Lead TSSOP (RU-14) 1 14 OUT D –IN D +IN D V– +IN C –IN C OUT C SSM2275 4 5 SSM2475 7 8 The SSM2275 and SSM2475 use the Butler Amplifier front end, which bines 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.

Key Features

  • Single or Dual-Supply Operation Excellent Sonic Characteristics Low Noise: 7 nV/√Hz Low THD: 0.0006% Rail-to-Rail Output High Output Current: ؎50 mA Low Supply Current: 1.7 mA/Amplifier Wide Bandwidth: 8 MHz High Slew Rate: 12 V/␮ s No Phase Reversal Unity Gain Stable Stable Parameters Over Temperature.
