ADS1292R评估套件

白小白_3003415

ADS1292R评估套件具有2声道、24位模拟前端(AFE)，内置可编程增益放大器(PGA)，安装有板上振荡器，是一个可多通道同时采样的24位模数转换器(ADC)。TI ADS1292R incorporates all the features commonly required in portable, low-power medical electrocardiogram (ECG), sports, and fitness applications. This TI AFE features high levels of integration and exceptional performance, enabling the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. ADS1292R has a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection.产品特性
