Key Features
- 8-channel 12-bit SAR ADC with configurable single-ended or differential inputs for versatile multi-sensor acquisition
- SPI-compatible 3-wire serial interface enables direct connection to microcontrollers and FPGAs without glue logic
- Sub-6 µs conversion time at up to 100 ksps in a through-hole 16-pin PDIP for easy prototyping and low-volume production
Applications
The MCP3208-BI/P is well suited for multi-channel analog data acquisition in industrial process monitoring, environmental sensing, and laboratory instruments requiring 12-bit resolution across 8 independent channels. Its SPI interface allows daisy-chaining or simple chip-select multiplexing with standard microcontrollers such as Arduino, PIC, and ARM Cortex-M, minimizing the GPIO pin count needed for analog expansion. The 16-pin PDIP package allows straightforward breadboard prototyping and socket-based field replacement in measurement equipment.

Frequently Asked Questions
How many analog channels does the MCP3208-BI/P provide, and can they be used in differential mode simultaneously?
The MCP3208-BI/P offers 8 single-ended channels or up to 4 fully differential input pairs, selectable per channel via the SPI command byte. In a differential configuration each pair rejects common-mode noise up to the common-mode input range, making it suitable for measuring bridge sensors, thermocouple amplifier outputs, and 4–20 mA current loop signals with 12-bit resolution and linearity error below 0.025%.
What is the maximum sampling rate of the MCP3208-BI/P, and is it sufficient for audio or vibration monitoring applications?
The MCP3208-BI/P achieves up to 100 ksps at a 5 V supply with a maximum conversion time of 6 µs per channel. For an 8-channel scan, the aggregate throughput per channel drops to 12.5 ksps, which covers low-frequency vibration (< 5 kHz bandwidth) and industrial process variables but falls short of audio-quality 44.1 ksps single-channel sampling, making it best suited for DC to 5 kHz sensor measurements.
What is the linearity error specification of the MCP3208-BI/P and what measurement accuracy does that represent?
The MCP3208-BI/P specifies a maximum integral linearity error of 0.0244%, equivalent to approximately 1 LSB across the 12-bit full-scale range (4096 counts). At a 5 V reference, 1 LSB corresponds to 1.22 mV of error, which is adequate for temperature, pressure, and strain measurements using common sensor amplifiers, and meets the accuracy requirements of most industrial 4–20 mA transmitter calibration systems.
How does the MCP3208-BI/P interface with a 3.3 V microcontroller when the ADC is powered from 5 V?
The MCP3208-BI/P accepts SPI clock and data inputs at logic levels compatible with its supply voltage, so at 5 V VDD the input high threshold is approximately 3.5 V. A 3.3 V microcontroller GPIO may not reliably drive the CS, CLK, and DIN pins above this threshold. The simplest solution is to either power the MCP3208 from 3.3 V (where it still operates at up to 50 ksps) or use a 3.3 V-to-5 V level shifter on the 3 SPI lines, keeping the DOUT line direct since it is an output from the ADC.
