Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and temperature range. Ensure that the selected variant matches the required pinout and thermal specifications for the intended PCB layout. Cross-reference the datasheet revision to confirm electrical characteristics align with design requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel high-resolution ADC is required. Compare channel count with MCP3561R (single channel) and MCP3564R (quad channel). Consider the internal voltage reference and oscillator availability if external components are to be minimized. Verify power supply constraints match the 2.7V-3.6V AVDD and 1.8V-3.6V DVDD ranges.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP3561/2/4R family of 24-bit Delta-Sigma ADCs. The '2' in the model number indicates a dual-channel architecture, distinguishing it from the single-channel MCP3561R and quad-channel MCP3564R. All variants share similar electrical characteristics and interface protocols but differ in input channel count and pin assignments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include MCP3561RT-E/NC for single-channel applications and MCP3564RT-E/NC for quad-channel requirements. Ensure pin compatibility and software register mapping remain consistent across the family during substitution.
