Texas Instruments ADS1292R 2-Channel, 24-Bit AFE

Texas Instruments ADS1292R 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. 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.
