Applications
The MCP3204-CI/ST is well-suited for data acquisition systems, industrial sensor interfaces, and battery-powered IoT nodes where 4 independent 12-bit analog channels must be read via a simple SPI bus from a low-power microcontroller running at 2.7V to 5.5V. Its 5V analog input range allows direct connection to standard 4–20 mA current loop transmitters with a shunt resistor, eliminating the need for analog front-end op-amps in many industrial measurement applications. The compact TSSOP-14 package makes it ideal for small embedded boards where board area is constrained but multi-channel analog acquisition is required.

Frequently Asked Questions
How many analog input channels does the MCP3204-CI/ST provide, and can they be configured as differential pairs?
The MCP3204-CI/ST provides 4 analog input channels that can be configured as either 4 single-ended inputs or 2 pseudo-differential pairs. In differential mode, each pair measures the difference between two inputs, improving noise rejection for sensor signals riding on a common-mode offset. This flexibility supports both single-ended 0V to 5V sensors and differential bridge outputs such as strain gauges within the same 12-bit, 4-channel IC.
What is the maximum conversion time for the MCP3204-CI/ST, and how does that translate to usable sample rate across all 4 channels?
The MCP3204-CI/ST completes a single 12-bit conversion in 6 µs maximum at the rated SPI clock speed. Sequentially scanning all 4 channels at maximum speed yields a per-channel sample rate of approximately 41 ksps, with a combined throughput of about 167 ksamples per second across all 4 inputs. For most industrial sensor applications sampling at 1 kHz to 10 kHz per channel, this conversion time provides ample throughput margin with a standard MCU SPI interface.
How does the MCP3204-CI/ST's 12-bit resolution and 0.0488% linearity error affect measurement accuracy for a 0V to 5V sensor input?
At 12-bit resolution over a 0V to 5V range, the MCP3204-CI/ST resolves steps of 5V / 4096 = 1.22 mV per LSB. The 0.0488% maximum linearity error corresponds to approximately 2 LSB of integral nonlinearity, meaning real-world measurement accuracy is within ±2.44 mV across the full input range. For temperature sensors, pressure transducers, or potentiometer position feedback converting physical quantities into 0V to 5V, this linearity is sufficient for most industrial control and monitoring applications.
For a portable data logger running from a 3.3V microcontroller, is the MCP3204-CI/ST compatible without additional interface circuitry?
Yes, the MCP3204-CI/ST operates from 2.7V to 5.5V supply and its SPI logic levels are referenced to VDD, so at 3.3V supply the device accepts 3.3V SPI signals directly without level shifting. The analog input range scales with VDD, giving a 0V to 3.3V full-scale range at 3.3V supply — the 12-bit resolution remains, resolving 0.806 mV per LSB. This direct 3.3V compatibility eliminates interface ICs, reducing BOM cost and standby current in battery-powered data loggers.
