Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description

SL8551 (single), SL8552 (dual) and SL8554 (quad) are high-precision, rail-to-rail input and output operational amplifiers. The chip uses offset correction technology, so it has very low offset voltage (typical value 2μV), and the offset voltage hardly changes with temperature and time.

The chip supports single power supply and dual power supply. When powered by a single power supply, its power supply voltage range is +2.3V to +5.5V; when powered by a dual power supply, its power supply voltage range is ±1. 15V to ±2.75V. The package types of SL8551 are mainly SC70-5, SOT23-5, MSOP-8 and SOP-8. The package types of SL8552 are mainly MSOP-8 and SOP-8. The package type of SL8554 is mainly SOP-14. And the operating temperature range for all package types is -40℃ to 125℃.
