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 MCP3204 is programmable to provide two pseudo-differential input pairs or four single-ended inputs, while the MCP3208 offers four pseudo-differential input pairs or eight single-ended inputs. These converters operate over a broad voltage range (2.7V - 5.5V) and boast low current design, making them suitable for battery-operated systems and process control applications. They are available in PDIP, SOIC, and TSSOP packages.
