The SGM8558-2XG is a dual, low noise, high precision CMOS operational amplifier that provides a high output current of 230mA, rail-to-rail output operation from a range of 2.8V to 5.5V single supply.
The SGM8558-2XG offers low input offset voltage, low input offset voltage drift and high output current drive. The device also can achieve a high 15MHz gain-bandwidth product and a high 8V/μs slew rate.
The SGM8558-2XG is specifically designed to drive high current load, such as 32Ω headset, VBIAS of RF power amplifier, etc.
The SGM8558-2XG is available in a Green WLCSP-1.45×1.45-8B package. It operates over an ambient temperature range of -40℃ to +125℃.
