MCP33111D-10-E/MS

Analog To Digital Converters (ADC) Overview

The MCP33111D-10-E/MS is a single-channel, fully differential 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Microchip Technology. It operates at a throughput rate of 1 Msps with no output latency. The device requires an analog supply voltage (AVDD) of 1.8 V and supports digital I/O interface voltages (DVIO) ranging from 1.7 V to 5.5 V. An external reference voltage (VREF) between 2.5 V and 5.1 V sets the input full-scale range from -VREF to +VREF. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 73.9 dBFS, Spurious Free Dynamic Range (SFDR) of 99.3 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 sampling rate
• Fully differential input operation with wide dynamic range defined by external VREF
• Ultra-low current consumption: ~1.6 mA during conversion and ~0.8 µA in standby mode
• Integrated self-calibration for offset, gain, and linearity errors

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature grade (-40°C to +125°C) as specified in the datasheet. Confirm the package type is MSOP-10. Ensure the external reference voltage source meets the 2.5 V to 5.1 V requirement and decoupling capacitors are placed on AVDD, DVIO, and VREF pins per design guidelines.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed, low-power ADC with differential inputs is required. The 12-bit resolution and 1 Msps speed suit applications needing moderate precision at high throughput. Ensure the host microcontroller supports SPI communication up to 100 MHz and can provide the necessary DVIO voltage levels within the 1.7 V to 5.5 V range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP331x1D-XX family, which includes 16-bit (MCP33131D), 14-bit (MCP33121D), and 12-bit (MCP33111D) variants. The '-10' suffix indicates a 1 Msps sample rate, while '-05' denotes 500 kSPs. The 'E' suffix specifies the automotive-grade temperature range, and '/MS' identifies the MSOP-10 package option.

Analog To Digital Converters (ADC) Replacement Considerations

Other members of the MCP331xxD-10 family may serve as alternatives if different resolution or package options are acceptable. For example, MCP33121D-10 offers 14-bit resolution, and MCP33131D-10 provides 16-bit resolution. Ensure pin compatibility and electrical specifications match the system requirements before substitution.
