MCP3204T-BI/SL

Analog To Digital Converters (ADC) Overview

The MCP3204T-BI/SL is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Microchip Technology. It features four programmable input channels that can be configured as single-ended or pseudo-differential pairs. The device operates on a single supply voltage ranging from 2.7V to 5.5V and supports a maximum sampling rate of 100 ksps at 5V, reducing to 50 ksps at 2.7V. Communication is handled via an SPI serial interface compatible with modes 0,0 and 1,1. Key electrical specifications include ±1 LSB maximum differential nonlinearity (DNL) and ±1 LSB maximum integral nonlinearity (INL). The component is housed in a 14-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'T' suffix indicates tape and reel packaging and the 'BI' suffix denotes industrial temperature range (-40°C to +85°C) per official documentation. Confirm pinout compatibility with the 14-pin SOIC footprint. Ensure the design accounts for the specific SPI timing requirements and reference voltage configurations outlined in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four 12-bit ADC channels are required within an industrial temperature range. Consider the 100 ksps sampling limit at 5V and the reduced 50 ksps rate at 2.7V. Verify that the source impedance of the analog inputs allows for accurate charging of the internal sample capacitor within the specified clock cycles to maintain linearity specifications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP3204/3208 family of 2.7V to 5.5V A/D converters. The MCP3204 variant specifically provides four input channels, whereas the MCP3208 offers eight. Both share the same SAR architecture and SPI interface capabilities but differ in channel count and package pin configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the MCP3204-CI/SL for commercial temperature range applications. For systems requiring eight channels, the MCP3208 series is the appropriate alternative. Ensure any substitute maintains the 12-bit resolution and SPI compatibility.
