- 2-channel differential or pseudo-differential input modes increase measurement flexibility for sensor bridge and ratiometric applications
- 2.7 V to 5.5 V supply range operates directly from 3.3 V and 5 V MCU systems without a separate regulator
- Maximum 3.125 µs conversion time supports sample rates up to 200 kSPS for real-time sensor monitoring
- Compact 8-pin SOIC package and minimal external component count simplify PCB layout and reduce BOM cost
Applications
The MCP3002-I/SN is widely used in microcontroller-based data acquisition systems, remote sensor nodes, and industrial monitoring equipment where a simple 2-channel 10-bit SPI ADC is needed with minimal external components. Its wide 2.7 V to 5.5 V supply compatibility makes it a straightforward choice for both 3.3 V ARM Cortex-M and 5 V AVR microcontroller designs reading temperature, pressure, or light sensors. The device is also used in portable battery monitors, motor position feedback circuits, and educational electronics platforms such as Raspberry Pi and Arduino add-on boards.

Frequently Asked Questions
What SPI clock speed does the MCP3002-I/SN support and how does that limit sample rate?
The MCP3002-I/SN supports SPI clock speeds up to 3.2 MHz at 5 V supply and up to 1.2 MHz at 2.7 V supply. At 3.2 MHz and using the required 16 clock cycles per conversion, the maximum achievable sample rate is 200 kSPS at 5 V, sufficient for audio-frequency sensor sampling, motor speed feedback, and slow process control loops running at 10 kHz to 100 kHz bandwidth.
Can the MCP3002-I/SN measure differential signals and what is the benefit in sensor circuits?
Yes, the MCP3002-I/SN supports both single-ended and pseudo-differential input modes on its 2 channels, allowing it to measure the voltage difference between two inputs and reject common-mode noise. In a resistive bridge sensor application with a 5 V excitation, differential mode doubles the effective input sensitivity to ±5 V full scale while providing up to 40 dB of common-mode noise rejection versus a single-ended connection.
How does the MCP3002-I/SN connect to an Arduino or Raspberry Pi for analog sensing?
The MCP3002-I/SN connects to any microcontroller or single-board computer via a 4-wire SPI bus: chip select (CS), clock (CLK), data in (DIN), and data out (DOUT), plus power and ground. On a 3.3 V Raspberry Pi, the device operates from the 3.3 V GPIO supply with no additional components, reading up to 2 analog channels at 75 kSPS for sensors such as potentiometers, light-dependent resistors, or thermistors.
What accuracy does the MCP3002-I/SN achieve and is it sufficient for temperature measurement?
The MCP3002-I/SN achieves a maximum linearity error of 0.0977% (approximately ±1 LSB at 10-bit resolution) over its full 0 V to Vdd input range. For a 0°C to 100°C temperature measurement using a sensor with 10 mV/°C sensitivity on a 5 V supply, 10-bit resolution provides approximately 0.1°C per LSB, making the MCP3002-I/SN accurate enough for heating, ventilation, and process monitoring applications with ±1°C requirements.
