The Microchip Technology Inc. MCP3204/3208 devices are successive approximation 12-bit Analog-to-Digital (A/D) Converters with on-board sample and hold circuitry. The MCP3208 is programmable to provide four pseudo-differential input pairs or eight single-ended inputs. It operates over a broad voltage range (2.7V - 5.5V) and features low current design, making it suitable for sensor interfaces, process control, data acquisition, and battery-operated systems.
