Applications
The MCP3204-CI/SL is used in multi-channel data acquisition systems, environmental monitoring instruments, and industrial control equipment where up to 4 analog sensor signals need to be digitized with 12-bit accuracy over a standard SPI bus. Its fast 6 µs conversion time allows scanning all 4 channels at sampling rates suitable for audio frequency signal monitoring and battery stack voltage measurement. The SOIC-14 package and SPI interface make it straightforward to add 4-channel ADC capability to any microcontroller-based design with minimal external components.

Frequently Asked Questions
How many analog input channels does the MCP3204-CI/SL provide and how can they be configured?
The MCP3204-CI/SL provides 4 analog input channels that can be configured individually as 4 single-ended inputs referenced to ground, or paired as 2 pseudo-differential channels for common-mode noise rejection. This flexibility lets designers choose the configuration best suited to their sensor interface, whether measuring absolute voltage levels with single-ended inputs or rejecting cable-induced noise with differential inputs.
How fast can the MCP3204-CI/SL convert analog signals and what is the achievable sample rate?
The MCP3204-CI/SL has a maximum conversion time of 6 µs per channel, corresponding to a maximum sample rate of approximately 100 kSPS at a 1 MHz SPI clock. This is fast enough for most industrial sensor polling and battery monitoring applications, and the SPI interface allows a microcontroller to initiate conversions and retrieve 12-bit results with minimal CPU overhead using DMA.
What is the linearity accuracy of the MCP3204-CI/SL and is it suitable for precision measurement?
The MCP3204-CI/SL specifies a maximum linearity error of 0.0488% of full scale, which corresponds to less than ±2 LSB error across the 12-bit output range of 4096 codes. This level of accuracy is suitable for temperature sensor digitization, battery voltage monitoring, and position sensor readouts where relative accuracy matters, though applications requiring better than 0.01% accuracy should use a higher-grade ADC with a precision external reference.
Can the MCP3204-CI/SL be used directly with a 3.3 V microcontroller, and does it need an external reference?
The MCP3204-CI/SL uses VDD as its internal reference, so it operates correctly at either 3.3 V or 5 V supply, accepting analog inputs up to the VDD level (5 V maximum absolute). When interfacing with a 3.3 V microcontroller, the SPI logic levels are compatible at 3.3 V VDD. No external voltage reference is required, simplifying the BOM, but if VDD noise exceeds a few mV, adding a 10 µF bulk capacitor plus a 100 nF ceramic decoupling capacitor on the VDD pin is recommended to maximize ADC accuracy.
