MCP33111-10-E/MS

Analog To Digital Converters (ADC) Overview

The MCP33111-10-E/MS is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter from Microchip Technology. It operates at a throughput rate of 1 Msps with no output latency. The device features pseudo-differential input operation supporting a full-scale range from 0V to +VREF. It requires an analog supply voltage (AVDD) of 1.8V and a digital I/O interface voltage (DVIO) ranging from 1.7V to 5.5V. An external reference voltage (VREF) between 2.5V and 5.1V is required. Typical performance metrics include a Signal-to-Noise Ratio (SNR) of 73.8 dBFS, Spurious Free Dynamic Range (SFDR) of 95.9 dB, Integral Nonlinearity (INL) of ±0.12 LSB, and Differential Nonlinearity (DNL) of ±0.06 LSB.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed no missing codes and 1 Msps throughput
• Pseudo-differential input configuration with 0V to +VREF full-scale range
• Wide digital I/O voltage range (1.7V to 5.5V) for direct host interfacing
• Internal self-calibration for offset, gain, and linearity errors

Analog To Digital Converters (ADC) Applications

• High-Precision Data Acquisition
• Medical Instruments
• Test Equipment
• Electric Vehicle Battery Management Systems
• Motor Control Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '-E' corresponds to the extended temperature grade (-40°C to +125°C) as defined in the official datasheet. Confirm the package type 'MS' indicates the MSOP-10 form factor. Ensure compatibility with the required external reference voltage range of 2.5V to 5.1V during component sourcing.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 12-bit accuracy at 1 Msps sampling rates. It is suitable for systems needing low power consumption, with typical standby current under 1 µA. The wide DVIO range allows integration with various microcontrollers without level shifters. Ensure the application supports single-ended or pseudo-differential input configurations rather than fully differential signals.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MCP331x1-XX family of SAR ADCs, which also includes 14-bit (MCP33121) and 16-bit (MCP33131) variants. The family shares similar architectural features, including self-calibration capabilities and SPI-compatible interfaces. The '-10' suffix denotes the 1 Msps sampling rate variant, distinct from the 500 kSPS '-05' version.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include MCP33121-10-E/MS (14-bit) and MCP33131-10-E/MS (16-bit), offering higher resolution at the same speed. For lower speed requirements, MCP33111-05-E/MS provides 500 kSPS operation. Pinout compatibility is maintained across these variants.
