Description

The MCP3204 12-bit Analog-to-Digital Converter (ADC) combines high performance and low power consumption in a small package, making it ideal for embedded control applications. The MCP3204 features a successive approximation register (SAR) architecture and an industry-standard SPI? serial interface, allowing 12-bit ADC capability to be added to any PICmicro? microcontroller. The MCP3204 features 100k samples/second, 4 input channels, low power consumption (5nA typical standby, 400 A max. active), and is available in 14-pin PDIP, SOIC and TSSOP packages. Applications for the MCP3204 include data acquisition, instrumentation and measurement, multi-channel data loggers, industrial PCs, motor control, robotics, industrial automation, smart sensors, portable instrumentation and home medical appliances.
