Description
The Intersil ISL43640 is a precision, bidirectional, analog switch configured as a 4 channel multiplexer/demultiplexer. The ISL43640 is designed to operate from a single +2V to +12V supply. It is equipped with an inhibit pin to simultaneously open all signal paths. ON resistance is 115Ω with a +5V supply, 45Ω with a +12V supply, and 190Ω with a +3V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 1nA at 25°C or 2. 5nA at 85°C. All digital inputs have 0. 8V to 2. 4V logic thresholds ensuring TTL/CMOS logic compatibility when using a single +5V supply. Some of the smallest packages are available, alleviating board space limitations, and making Intersil's newest line of low-voltage switches an ideal solution.

It explains the use of specific wavelengths (660nm, 805nm, 940nm) to measure oxygen saturation via photodiodes and highlights the need for precise, low-noise amplifiers and 16-bit ADCs. It emphasizes balancing power consumption, noise, resolution, and portability in medical device design. The document also includes a block diagram for pulse oximetry and outlines Renesas Electronics’ product quality classifications and legal disclaimers.
- Application NotePDF 843 KB an535 Jun 05, 2002AI-generated Summary: A Data Acquisition System (DAS) requires careful design of signal conditioning, transducer selection, and signal transmission to ensure high accuracy. Signal conditioning includes multiplexing, amplification, filtering, and calibration, ideally performed near the transducer. Transducers convert physical variables to electrical signals, often voltage, with low source resistance preferred. Signal paths can be single-ended or differential; differential paths better reject common mode noise, especially for low-level signals. Shielded twisted pairs and balanced lines reduce interference. Filters, typically Butterworth low-pass, prevent aliasing and maintain signal integrity.
