Microchip MCP3204/3208 12-Bit A/D Converters Datasheet
The Microchip MCP3204/3208 devices are 12-bit successive approximation analog-to-digital (A/D) converters featuring on-board sample and hold circuitry. The MCP3204 supports four input channels, while the MCP3208 supports eight, with inputs programmable as single-ended or pseudo-differential pairs. Communication is handled via a simple serial interface compatible with the SPI protocol.
These devices operate over a broad voltage range of 2.7V to 5.5V and offer high sampling rates of up to 100 ksps at 5V. They are designed for low power consumption, with typical standby currents of 500 nA and active currents of 400 µA at 5V. The datasheet provides comprehensive electrical specifications, including resolution, integral and differential nonlinearity, and dynamic performance metrics.
