The TIDM-1002 reference design helps designers develop an ultrasonic gas metering sub-system using a unique proprietary algorithm and an analog-to-digital converter (ADC) based sampling technique. The TIDM-1002 is based on a 256-KB MSP430™ microcontroller (MCU): the MSP430FR5994: with integrated low energy accelerator (LEA) for digital signal processing and discrete analog front end (AFE) chipsets: which provide superior metrology performance with low-power consumption.
