Applications
The MCP3461RT-E/NC suits miniaturized IoT sensing nodes and wearable devices where board space is critical, thanks to its tiny UQFN-20 footprint combined with 16-bit resolution. Industrial process control applications including temperature measurement with thermocouples, RTD interfaces, and pressure sensor digitization benefit from its integrated voltage reference and programmable gain amplifier operating across the -40°C to 125°C range. Its low-power SPI-based architecture also makes it a strong fit for battery-operated portable diagnostic equipment.

Frequently Asked Questions
How does the UQFN-20 package of MCP3461RT-E/NC compare to the TSSOP-20 version for high-density PCB designs?
The UQFN-20 package measures approximately 3 mm × 3 mm, offering a significantly smaller footprint than the TSSOP-20 used on the MCP3461R-E/ST. This allows engineers designing compact IoT modules or wearable sensor nodes to achieve the same 16-bit, 153.6 kSPS delta-sigma performance in roughly one-quarter the PCB area, with thermal performance improved by the exposed pad.
What programmable gain settings does MCP3461RT-E/NC support for direct sensor connection?
The integrated PGA supports gain values of 1/3, 1, 2, 4, 8, 16, 32, and 64, covering input signal ranges from small millivolt bridge outputs up to ±3.6 V full-scale. This flexibility allows direct connection to 4–20 mA current-loop transducers, strain gauges, and thermocouples in 3.3 V industrial systems without external gain-setting resistors or op-amps.
What operating temperature range does MCP3461RT-E/NC support for industrial deployments?
The MCP3461RT-E/NC is rated for -40°C to 125°C ambient temperature operation, meeting industrial-grade requirements for factory automation, outdoor environmental monitoring, and automotive auxiliary systems. Combined with the internal oscillator and voltage reference, it can deliver consistent 16-bit accuracy across the full temperature range without external calibration components.
In what scenario would MCP3461RT-E/NC be preferred over an external-reference ADC such as MCP3461-E/NC?
When BOM cost reduction and PCB area minimization are primary design constraints in a 3.3 V single-supply system, the MCP3461RT-E/NC is preferred because its integrated 2.4 V reference and internal oscillator remove two external components. For applications achieving less than 1 LSB INL error at 16-bit resolution while keeping the solution footprint under 10 mm², this variant offers the best integration level in the MCP346x family.
