AFE159x 4-Channel 24-Bit Analog Front-Ends (AFEs)

Texas Instruments AFE159x 4-Channel 24-Bit Analog Front-Ends (AFEs) are a family of multichannel, 24-bit, simultaneous sampling, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with built-in programmable gain Instrumentation Amplifiers (INAs), internal reference, and an on-chip PLL. The AFE supports digital pace pulse detection and thoracic impedance measurement and incorporates all of the features commonly required in medical electroencephalogram (EEG) and electrocardiogram (ECG) applications. Multiple Texas Instruments AFE159x devices can be cascaded in high channel count systems. With exceptional performance and high levels of integration, the AFE159x enables the development of scalable medical instrumentation systems at significantly reduced power, size, and overall cost.
