12-bit Analog-to-Digital Converter (ADC) with 8 input channels, featuring a 52 kS/s conversion rate and SPI interface. This data acquisition system integrates a multiplexer (MUX), programmable gain amplifier (PGA), and internal reference. Operating from a 2.7V to 5.25V supply, it offers 0.5 LSB differential nonlinearity and 2.5 LSB integral nonlinearity. Packaged in a 28-pin SSOP with gold contact plating, this lead-free component operates across a -40°C to 85°C temperature range.
