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:

SL7887 is a 10-bit ADC (Analog-to-Digital Converter) chip, which has the basic characteristics of high resolution, high speed, low power consumption, small size and uni polarity. The product is divided into two versions:

The SL7887 version is powered by a single power supply of 4 V-5.25 V, and the 12-bit high-resolution high-speed 3.3V-5.25V sampling rate can reach up to 800 KSPS. The SL7887E version is powered by a single power supply of 3.3 V-4.8 V, and the sampling rate can reach up to 1250 KSPS. Both versions are packaged in a 6-pin SOT-23 package with an operating temperature range of -40 to 85.SL7887 is a pin-to-pin replacement for ADS7887 with less than 1/2 of the average dynamic power consumption, significantly extending the battery operating time.
