Frequently Asked Questions
How many analog channels does MCP3564RT-E/ST provide and what is the input voltage range?
The MCP3564RT-E/ST provides 8 analog input channels configurable as up to 4 differential pairs. The input voltage range spans -2.7 V to 3.6 V, accommodating a wide variety of sensor output signals including bridge transducers, thermocouples, and resistive dividers in 3 V single-supply measurement systems.
What resolution and linearity does MCP3564RT-E/ST deliver in precision industrial measurement?
The MCP3564RT-E/ST delivers 24-bit resolution with a maximum linearity error of 0.0032%, enabling highly accurate measurements in industrial scales, pressure sensors, and chemical analyzers. This linearity specification supports sub-ppm level analog-to-digital conversion performance critical in calibration-grade metrology instruments.
How does the integrated voltage reference in MCP3564RT-E/ST simplify sensor interface circuit design?
The onboard internal voltage reference eliminates the need for a discrete precision reference IC on sensor interface boards, reducing component count and PCB area. This integration lowers BOM cost in multi-channel data acquisition systems where each analog channel would otherwise require its own buffered reference voltage connection.
When is MCP3564RT-E/ST preferable over MCP3461 for a multi-channel temperature logging application?
MCP3564RT-E/ST is preferred when 8 input channels are needed to simultaneously scan multiple thermocouple or RTD sensors versus MCP3461 which provides only 2 channels. Both offer 24-bit delta-sigma performance, but the 8-channel version reduces external multiplexer requirements and simplifies firmware scan sequencing in temperature logging systems with 5 or more sensors.
