The GP9101-F1K-L2H1-SW is an ADC/DAC, SOP-8, specialized RoHS part manufactured by Guestgood. It is a low power monolithic ADC/DAC IC with 8-bit resolution, referred to as a "digital-to-analog converter (DAC), which converts digital signals (input) to analog signals (output). It is ideal for projects that require accurate low power analog signals, such as in digital audio applications. The device has a total resolution of 8 bits, allowing for highly accurate digital signal conversion to analog signals. It is a RoHS compliant part, meaning that it has been designed to be lead-free, and does not contain hazardous substances. This makes it an ideal choice for any project that requires compliance with RoHS regulations.
