MCP3201-BI/SN

Analog To Digital Converters (ADC) Overview

The MCP3201-BI/SN is a Microchip Technology successive approximation register (SAR) analog-to-digital converter featuring 12-bit resolution and a single pseudo-differential input. It operates on a single supply voltage ranging from 2.7V to 5.5V, supporting maximum sampling rates of 100 ksps at 5V and 50 ksps at 2.7V. The device utilizes an SPI-compatible serial interface for communication and includes an onboard sample-and-hold circuit. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'SN' corresponds to the 8-pin SOIC package and the 'BI' indicates the industrial temperature grade (-40°C to +85°C). Confirm that the specific lot meets RoHS compliance standards as required by the project specifications. Ensure the ordering quantity matches the standard tube packaging typically associated with this surface-mount variant.

Analog To Digital Converters (ADC) Selection Notes

Select the MCP3201-BI/SN when a single-channel 12-bit conversion is required with low power consumption. The -B grade ensures tighter integral nonlinearity specifications compared to the -C grade. This part is suitable for systems requiring a pseudo-differential input configuration to reject common-mode noise while maintaining compatibility with standard SPI microcontroller interfaces.

Analog To Digital Converters (ADC) Part Context

The MCP3201 belongs to the MCP3201 series of 12-bit A/D converters. It shares architectural similarities with other members like the MCP3202 but differs in channel count. The 'SN' suffix specifically denotes the 8-lead Small Outline Integrated Circuit (SOIC) package, distinguishing it from PDIP, MSOP, or TSSOP variants within the same electrical family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include other MCP3201 variants such as MCP3201-CI/SN or MCP3201-BI/PDIP, provided the package type and temperature grade meet the design requirements. Cross-model substitution with MCP3202 requires accounting for the additional channel availability.
