Analog-to-Digital Converters (ADCs) are crucial components in digital systems, responsible for converting analog signals into digital form. The 8-bit ADC is a popular choice due to its moderate resolution and relatively low cost. This specific device is the 8 Bit Analog to Digital Converter with 4 or 8 input channels, utilizing a Successive Approximation Register (SAR) architecture. It features a compact 20-pin Small Shrink Outline Package (SSOP).
