Applications
The MCP3202-CI/SN is used in embedded sensor acquisition systems where 12-bit precision digitization of analog signals such as temperature, pressure, or light intensity is required over an SPI bus. It is well suited for battery-powered data loggers and IoT sensor nodes operating from a 2.7 V to 5.5 V supply, thanks to its low power consumption and fast 6.66 µs conversion time. Industrial control panels and portable instruments also use it to read potentiometer positions or 0–5 V process signals with minimal external components.

Frequently Asked Questions
What resolution and conversion speed does the MCP3202-CI/SN provide for sensor digitization tasks?
The MCP3202-CI/SN delivers 12-bit resolution with a maximum conversion time of 6.66 µs, enabling up to approximately 150 ksps throughput. This combination suits real-time sensor monitoring where signal fidelity and acquisition speed must both be maintained without overloading a low-power microcontroller.
How should an engineer configure the MCP3202-CI/SN input channels when measuring a differential sensor signal versus two independent single-ended signals?
The MCP3202-CI/SN supports both modes via the SPI command byte: setting the SGL/DIFF bit low selects pseudo-differential mode across channels 0 and 1, which rejects common-mode noise up to the analog input range of 5.5 V; setting it high enables 2 independent single-ended channels each referenced to AGND for straightforward potentiometer or voltage divider readings.
What supply voltage range does the MCP3202-CI/SN support, and does it operate correctly in a 3.3 V microcontroller system?
The MCP3202-CI/SN operates from 2.7 V to 5.5 V, making it fully compatible with 3.3 V systems. At 3.3 V the analog input range spans 0 V to 3.3 V with the same 12-bit resolution, and the SPI logic levels align with 3.3 V CMOS I/O without level translators, simplifying integration with modern low-voltage microcontrollers.
Which package does the MCP3202-CI/SN use and how does this benefit prototyping versus volume production?
The MCP3202-CI/SN is housed in a standard SOIC-8 package with 1.27 mm pin pitch, which fits soldering irons and hot-air rework stations for prototyping while also being supported by all SMT pick-and-place lines for high-volume production runs; the 8-pin footprint occupies approximately 5 mm x 4 mm of board area.
