TI TDC1000+MSP430超声波流量计参考设计
TI公司的TDC1000是全集成的模拟前端(AFE),用来测量汽车,工业和消费类电子的水位,液体浓度,流量和接近距离,和TI的MSP430/C2000 MCU一起使用,提供完整的超声波检测解决方案.本文介绍了TDC1000主要特性,功能框图和几种应用电路,以及汽车超声波液体流量测量参考设计TIDA-00322主要特性,电路图和材料清单.
The TDC1000 is a fully integrated analog front-end (AFE) for ultrasonic sensing measurements of level, fluid identification/concentration, flow, and proximity/ distance applications common in automotive, industrial, medical, and consumer markets. When paired with an MSP430/C2000 MCU, power, wireless, and source code, TI provides the complete ultrasonic sensing solution.
TI’s Ultrasonic AFE offers programmability and flexibility to accommodate a wide-range of applications and end equipment. The TDC1000 can be configured for multiple transmit pulses and frequencies, gain, and signal thresholds for use with a wide-range of transducer frequencies (31.25kHz to 4MHz) and Q-factors. Similarly, the programmability of the receive path allows ultrasonic waves to be detected over a wider range of distances/tank sizes and through various mediums.
