SGM8558-3数据手册SGMICRO中文资料规格书

描述 Description

The SGM8558-1 (single), SGM8558-2 (dual), SGM8558-3 (single with shutdown), and SGM8558-4 (quad) are low noise, high precision CMOS operational amplifiers that provide a high output current of 230mA, rail-to-rail output operation from a range of 2.8V to 5.5V single supply. The SGM8558-3 is available with shutdown pins that drive the output voltage low.
The SGM8558-1/2/3/4 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 8V/μs slew rate.
The SGM8558-1/2/3/4 are specifically designed to drive high current load, such as 32Ω headset, VBIAS of RF power amplifier, etc.
The SGM8558-1 is available in Green SOIC-8 and SOT-23-5 packages. The SGM8558-2 is available in Green TDFN-3×3-8L and SOIC-8 packages. The SGM8558-3 is available in a Green SOT-23-6 package. The SGM8558-4 is available in a Green SOIC-14 package. They operate over an ambient temperature range of -40℃ to +125℃.
