The SGM8557-1 (single), SGM8557-3 (single with shutdown), SGM8557-2 (dual) and SGM8557-5 (dual with shutdown) are low noise, high precision CMOS operational amplifiers that provide a high output current of 240mA, rail-to-rail output operation from a range of 2.7V to 5.5V single supply. The SGM8557-3/5 are both available with shutdown pins that drive the output voltage low.

The SGM8557-1/2/3/5 offer low input offset voltage, low input offset voltage drift and high output current drive. These devices also can achieve a high 15MHz gain-bandwidth product and a high 7V/μs slew rate.

The SGM8557-1/2/3/5 are specifically designed to drive high current load, such as 32Ω headset, VBIAS of RF power amplifier, etc.

The SGM8557-1 is available in Green SOIC-8, MSOP-8 and SOT-23-5 packages. The SGM8557-2 is available in a Green SOIC-8 package. The SGM8557-3 is available in Green SOIC-8 and SOT-23-6 packages. The SGM8557-5 is available in a Green MSOP-10 package. They operate over an ambient temperature range of -40 to +125.
