What are the key features of ADUCM360?
- Dual 24-bit sigma-delta ADCs with programmable gain amplifier (PGA) up to 128x for high-resolution sensor measurement
- ARM Cortex-M3 core at 16 MHz enables on-chip signal processing eliminating external DSP or MCU
- Integrated excitation current sources and voltage reference support direct bridge sensor connections without external components
- Low-power design with deep-sleep modes suitable for battery-operated field instruments and smart transmitters
What is ADUCM360 used for?
ADUCM360 is used in precision industrial process transmitters, chemical analyzers, and weigh scale systems that require simultaneous dual-channel 24-bit ADC conversion with integrated signal conditioning. The on-chip ARM Cortex-M3 processor handles digital filtering, calibration, and HART or SPI communication without an external MCU. Its integrated excitation sources and PGA enable direct connection to strain gauge bridges, RTDs, thermocouples, and conductivity cells in portable field instruments.

Frequently Asked Questions
What ADC resolution does ADUCM360 provide, and how does it compare to typical 16-bit ADC microcontrollers?
ADUCM360 integrates dual 24-bit sigma-delta ADCs providing up to 16,777,216 discrete levels versus 65,536 levels in 16-bit designs. This 256x higher resolution allows measuring bridge sensor outputs as small as 10 nV equivalent noise, enabling sub-ppm accuracy in precision weigh scales and laboratory analyzers that a 16-bit converter cannot achieve.
Can ADUCM360 directly interface with a Wheatstone bridge sensor without external signal conditioning?
ADUCM360 includes integrated programmable gain amplifiers up to 128x and on-chip excitation current sources of 100 µA to 2 mA, allowing direct connection to 350 Ω Wheatstone bridge strain gauges without external instrumentation amplifiers or excitation circuits. The dual 24-bit ADC can simultaneously sample both differential bridge outputs for ratiometric measurements.
What processor does ADUCM360 embed, and what clock frequency does it support for real-time signal processing?
ADUCM360 integrates an ARM Cortex-M3 processor running at up to 16 MHz, delivering 16 DMIPS of processing performance for on-chip digital filtering, linearization algorithms, and communication protocols. This eliminates the need for a separate MCU in smart sensor transmitters, reducing BOM cost and PCB area compared to discrete ADC-plus-processor solutions.
How much flash and RAM does ADUCM360 provide for embedded application code and data buffers?
ADUCM360 provides 128 KB of flash program memory and 8 KB of SRAM for application code, calibration tables, and real-time data buffers. The 128 KB flash accommodates IIR/FIR filter coefficients, multi-point calibration curves, and a HART communication stack simultaneously, covering typical precision transmitter firmware requirements without external memory.
