Applications
The MCP3464R-E/ST is designed for precision data acquisition in industrial process control, environmental monitoring, and scientific instrumentation where 16-bit resolution across 8 channels is needed on a single 3V supply. Its integrated voltage reference simplifies board design for multi-channel sensor readout in temperature measurement bridges, pressure sensing arrays, and strain gauge networks. The delta-sigma architecture with programmable oversampling also suits audio-frequency signal analysis and electrochemical sensor readout where noise rejection and resolution take priority over raw sampling speed.

Frequently Asked Questions
How many input channels does the MCP3464R-E/ST provide, and can they be configured differentially?
The MCP3464R-E/ST provides 8 analog input channels that can be configured as 8 single-ended inputs or up to 4 fully differential input pairs via the internal multiplexer. The differential input range extends to ±3.6V relative to the reference, supporting direct connection to bridge sensors, thermocouples, and other differential-output transducers without external level-shifting circuitry.
Does the MCP3464R-E/ST need an external voltage reference for accurate conversions?
No, the MCP3464R-E/ST includes an integrated precision voltage reference, eliminating the need for an external reference IC. This reduces BOM cost and PCB area while ensuring the 16-bit conversion accuracy is maintained across the -40°C to +125°C operating temperature range, which is especially valuable in multi-channel sensor nodes where adding a separate precision reference for each ADC would be costly.
For a precision industrial sensor hub reading 6 strain gauges, is MCP3464R-E/ST a suitable choice?
Yes, the MCP3464R-E/ST suits a 6-channel strain gauge hub well. Its 8 differential-capable inputs handle all 6 gauge bridges on one device, with 2 spare channels for temperature compensation. The 16-bit resolution resolves strain variations below 0.01% of full scale, the integrated reference removes calibration drift from a separate reference IC, and the TSSOP-20 package fits a compact sensor hub PCB operating from a single 3V supply.
