Frequently Asked Questions
How many analog channels can the MCP3004-I/ST sample, and can they be used differentially?
The MCP3004-I/ST provides 4 single-ended input channels or 2 differential input pairs, selectable through the SPI command word. Differential mode is particularly useful for reading Wheatstone bridge sensors and rejecting common-mode noise on long sensor cables, allowing accurate measurements in electrically noisy industrial environments without additional instrumentation amplifiers.
What maximum sample rate does the MCP3004-I/ST achieve, and which microcontroller SPI speeds support it?
With a maximum conversion time of 2.78 µs the MCP3004-I/ST supports up to 200 ksps at 3.3 V supply. The SPI clock must reach at least 1.35 MHz to sustain full throughput, which is well within the capability of virtually all modern 8-bit and 32-bit microcontrollers, including PIC, AVR, and ARM Cortex-M devices running at clock frequencies of 8 MHz or higher.
How does the MCP3004-I/ST's 0.098% maximum linearity error affect measurement accuracy in a 0-5 V temperature sensor circuit?
A maximum linearity error of 0.098% corresponds to about 1 LSB at 10-bit resolution over the full 5 V input range, meaning the ADC introduces at most 4.9 mV of non-linearity error. For a temperature sensor with 10 mV/°C sensitivity this translates to less than 0.5°C of measurement uncertainty from ADC non-linearity alone, which is acceptable for most HVAC and industrial temperature monitoring applications.
When is the MCP3004-I/ST a better fit than the 12-bit MCP3204 for a cost-sensitive data logger?
The MCP3004-I/ST is preferable when 10-bit resolution (1024 codes over the full input range) is sufficient for the measurement accuracy requirement and lower unit cost is a design priority. For signals with less than 0.1% noise and where 12-bit dynamic range is not needed — such as level sensing, coarse temperature monitoring, or user potentiometer inputs — the MCP3004 delivers adequate performance at a cost saving compared to the MCP3204.
