Key Features

  • 8 single-ended or 4 differential 12-bit ADC channels in one IC
  • Fast successive-approximation conversion in under 6 µs per sample
  • SPI-compatible serial interface supporting up to 2 MHz clock
  • Wide 5 V analog input range with 0.0488% maximum linearity error
  • 16-pin SOIC package with RoHS/Pb-free compliance (JESD-609 e3)

Applications

The MCP3208-CI/SL is widely used in embedded data-acquisition systems and microcontroller-based designs that need to digitize multiple analog sensor channels over a simple 3- or 4-wire SPI bus. It excels in industrial process monitoring, battery management, and environmental sensing applications where 12-bit resolution across 8 channels at up to 5 V is required without the cost or complexity of a dedicated high-speed converter. Its compact 16-pin SOIC footprint also makes it a popular choice for space-constrained boards in smart home devices, motor-control feedback loops, and portable test instruments.

Frequently Asked Questions

How many analog input channels does the MCP3208-CI/SL support, and can they be configured as differential pairs?

The MCP3208-CI/SL provides 8 single-ended input channels or 4 differential input pairs, selectable via the SPI command byte. Each channel accepts analog voltages from 0 V to 5 V, and the 12-bit successive-approximation architecture gives 4096 quantization levels across that range, suitable for reading temperature sensors, potentiometers, or pressure transducers without external multiplexers.

What conversion speed does the MCP3208-CI/SL achieve at its maximum SPI clock rate?

At the maximum recommended SPI clock of 2 MHz with a 5 V supply, the MCP3208-CI/SL completes each 12-bit conversion in approximately 6 µs maximum. This translates to a throughput of up to about 100 kSPS per channel when continuously cycling through all 8 inputs, which is adequate for slow-changing analog signals in industrial monitoring, HVAC control, and sensor fusion applications.

Which microcontroller families interface most easily with the MCP3208-CI/SL, and what is the wiring requirement?

The MCP3208-CI/SL uses a standard 4-wire SPI interface (CS, CLK, MOSI, MISO) operating at 2.7 V to 5.5 V, making it directly compatible with virtually any microcontroller family including AVR, PIC, STM32, ESP32, and Raspberry Pi. Only 4 digital I/O lines plus a shared power and ground connection are needed; no level-shifter is required when both devices share a 3.3 V or 5 V rail.

What is the linearity error of the MCP3208-CI/SL, and how does it affect 12-bit measurement accuracy?

The MCP3208-CI/SL specifies a maximum integral linearity error (EL) of 0.0488%, which corresponds to approximately ±1 LSB at 12-bit resolution. This means the converter's transfer function deviates by at most 2 counts out of 4096, preserving measurement integrity for instrumentation where sub-percent accuracy is required without trimming or calibration offsets.

What package and lead-finish options does the MCP3208-CI/SL offer, and what is a typical lead time?

The MCP3208-CI/SL is supplied in a 16-pin SOIC (R-PDSO-G16) package with a Pb-free, RoHS-compliant lead finish coded JESD-609 e3. Standard factory lead time is approximately 7 weeks, so procurement teams should plan safety stock or place blanket orders to avoid line-down risks, particularly in high-volume production runs.
