Semiconductors\Data Converter ICs\Analog Front End - AFE
ADS129x 2-Channel, 24-Bit AFETexas Instruments ADS129x 2-Channel, 24-Bit Analog Front End (AFE) is a multichannel, simultaneous sampling, 24-bit, delta-sigma analog-to-digital converter (ADC) with a built-in Programmable Gain Amplifier (PGA), internal reference, and an onboard oscillator. ADS129x incorporates all the features commonly required in portable, low-power medical electrocardiogram (ECG), sports, and fitness applications. This AFE features high levels of integration and exceptional performance. This feature enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. Texas Instruments ADS129x has a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection.
