Frequently Asked Questions
What resolution and conversion speed does the MCP3202-CI/P offer for sensor measurement applications?
The MCP3202-CI/P provides 12-bit resolution with a maximum conversion time of 6.66 µs, enabling sample rates exceeding 100 ksps in continuous conversion mode. The 12-bit resolution yields 4096 quantization levels, giving approximately 1.2 mV per LSB with a 5 V reference. This is suitable for measuring temperature sensors, pressure transducers, and potentiometers where 0.025% measurement resolution is required.
How does the differential input of the MCP3202-CI/P improve noise rejection in industrial environments?
The MCP3202-CI/P supports differential input mode where the ADC measures the voltage difference between two input pins rather than a single-ended signal relative to ground. This configuration rejects common-mode noise picked up equally on both input lines, which is critical in electrically noisy environments with motor drives, switching power supplies, or long cable runs. With 12-bit resolution and differential inputs, noise rejection is approximately equal to the common-mode rejection of the signal path.
What interface protocol does the MCP3202-CI/P use and how is it connected to a microcontroller?
The MCP3202-CI/P uses a 4-wire SPI-compatible serial interface (SCK, MOSI, MISO, CS) for communication with host microcontrollers, operating at clock speeds up to 1.8 MHz at 2.7 V and up to 3.2 MHz at 5 V supply. Connection requires only 4 GPIO pins on any microcontroller with SPI support, making it compatible with PIC, AVR, ARM Cortex-M, and Raspberry Pi platforms. The PDIP-8 package simplifies prototyping with standard 0.1-inch pitch breadboards.
What is the linearity error specification of the MCP3202-CI/P and how does it affect measurement accuracy?
The MCP3202-CI/P has a maximum linearity error (integral non-linearity) of 0.0488%, which corresponds to approximately 2 LSB at 12-bit resolution. This means the actual transfer curve deviates from an ideal straight line by no more than 2 counts across the full input range of 0 V to 5.5 V. For applications such as temperature measurement using a PT100 sensor or battery voltage monitoring, this level of linearity error introduces measurement uncertainty of less than 0.05%.
