MCP320X MCP320X 12-Bit Analog-to-Digital Converters Product Information The Microchip MCP320X MCP320X family of 12-bit analog-to-digital converters (ADCs) combines high performance and low power consumption in a small package ­ making it ideal for embedded control applications. Consisting of the MCP3201 MCP3201, MCP3202 MCP3202, MCP3204 MCP3204 and MCP3208 MCP3208, the MCP320X MCP320X family features a successive approximation register (SAR) architecture and an industrystandard SPITM serial interface. Devices are available with 1, 2, 4 or 8 input channels and in PDIP SOIC and TSSOP , packages. The MCP320X MCP320X family offers existing Microchip customers added flexibility when incorporating analog inputs into their designs. The industry standard SPI interface allows 12-bit ADC capability to be added to any PICmicro® microcontroller. In addition, new customers will find the performance and price of the MCP320X MCP320X family very attractive. Applications for the MCP320X MCP320X family include data acquisition, instrumentation and measurement, multichannel data loggers, industrial PCs, motor control, robotics, industrial automation, smart sensors, portable instrumentation and home medical appliances.
