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:

SL121S101 is a 12-bit ADC (Analog-to-Digital Converter) chip with the basic characteristics of high resolution, high speed, low power consumption, small size and unipolarity. The converter is based on a successive approximation register architecture with an internal sample-and- hold circuit. The converter is divided into two versions:

The SL121S101 version uses a single power supply of 4 V to 5.25 V, and its performance parameters cover 500KSPS to 800KSPS; The SL121S101E version uses a single power supply of 3.3 V to 4.8 V, and its performance parameters cover 800KSPS to 1000KSPS. Both versions are currently packaged in a 6-pin SOT-23 package with an operating temperature range of -40℃ to 85℃. SL121S101 can pin-to-pin replace ADC121S101, the dynamic power consumption at high voltage is less than 1/2, which significantly extends the battery operating time.
