Overview

The ADC add-on board provides four buffered 12-bit analogue inputs and is based on Microchip's MCP3204 A/D converter IC, which interfaces to microcontrollers serially by SPI bus. The board also features a Microchip MCP6284 rail-to-rail op-amp and 4.096V reference voltage. The board is ideal for use with your own prototype circuits and plugs directly into solderless breadboards.

MCP3204 12-bit Analogue-to-Digital Converter

Microchip Technology's MCP3204 12-bit Analogue-to-Digital Converter (ADC) combines high performance and low power consumption in a small package (14-pin), 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 SPI-equipped microcontroller. The MCP3204 features 100k samples/second, 4 input channels and low power consumption (5nA typical standby, 400 µA max. active). 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.
