MCP33111-10T-E/MN

Analog To Digital Converters (ADC) Overview

The MCP33111-10T-E/MN 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 pseudo-differential input capability and an external reference voltage range of 2.5V to 5.1V. The device requires a 1.8V analog supply (AVDD) and supports digital I/O voltages between 1.7V and 5.5V. Key electrical characteristics include a typical Signal-to-Noise Ratio (SNR) of 73.8 dBFS, Integral Nonlinearity (INL) of ±0.12 LSB, and Differential Nonlinearity (DNL) of ±0.06 LSB. Total power consumption is approximately 6.2 mW at 1 Msps. It features AEC-Q100 qualification for Grade 1 operation across -40°C to +125°C and utilizes a TDFN-10 package.

• High-Precision Data Acquisition
• Medical Instruments
• Electric Vehicle Battery Management Systems
• Motor Control Applications
• Switch-Mode Power Supply Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging and the 'E' suffix denotes extended temperature grade (-40°C to +125°C). Confirm the specific datasheet revision DS20006122A matches the required specifications. Ensure compatibility with the host system's SPI interface timing requirements, particularly regarding SCLK frequency limits relative to DVIO levels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended or pseudo-differential 12-bit ADC with high speed (1 Msps) and low power is required. It is suitable for applications needing wide digital I/O voltage flexibility (1.7V–5.5V) without level shifters. Consider the TDFN-10 package if space constraints favor surface-mount thermal pads over MSOP-10. Verify that the external reference voltage falls within the 2.5V to 5.1V range for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP33131/21/11-XX family of SAR ADCs. The '11' designation specifies 12-bit resolution, while '-10' indicates the 1 Msps sampling rate variant. The 'MCP33111-05' variant offers 500 kSPS. All variants share similar pinouts and operational characteristics but differ in resolution and maximum throughput.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. For equivalent performance, consider other members of the MCP331xxD-10 family such as MCP33111D-10-I/MS, noting differences in package type (MSOP vs. TDFN) and operating temperature grade.
