描述

The Intersil ISL84582 device is made of precision, bi-directional, analog switches configured as a differential 4-Channel multiplexer/demultiplexer. It is designed to operate from a single +2V to +12V supply or from a ±2V to ±6V dual supplies. The device has an inhibit pin to simultaneously open all signal paths. ON-resistance of 39Ω with a ±5V supply and 125Ω with a single +3. 3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0. 02nA at +25°C or 0. 2nA at +85°C. All digital inputs have 0. 8V to 2. 4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single 3. 3V or +5V supply or dual ±5V supplies. The ISL84582 is a differential 4-to-1 multiplexer device.

    AN535: Design Considerations for a Data Acquisition System (DAS)
    PDF 843 KB an535 2002年6月05日
    AI 生成的摘要: 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.

    AN557: Recommended Test Procedures for Analog Switches
    PDF 468 KB an557 2002年5月24日
    AI 生成的摘要: The document details recommended test procedures for analog switches, focusing on key parameters such as crosstalk, break-before-make delay, and settling time. It explains how to measure crosstalk using decibel ratios and outlines the importance of break-before-make delay to prevent simultaneous switch closure. Settling time is measured to ensure output stability after input changes. It also covers input thresholds, leakage currents, power dissipation, and various switch capacitances, providing test circuit examples and conditions for accurate measurement.

    AI 生成的摘要: The document discusses the use of analog switches and multiplexers in wideband applications, highlighting the HI-524 monolithic wideband CMOS multiplexer and the HA-2541 amplifier. It emphasizes the importance of unity gain stability, fast settling time, and output swing for driving coaxial cables. The HI-524 includes feedback resistance to minimize offset voltage. Proper layout is crucial to avoid feedthrough and excessive capacitance. The document also outlines Renesas Electronics' disclaimers on product use, quality grades, safety responsibilities, environmental compliance, and legal restrictions.

    AN520: CMOS Analog Multiplexers and Switches; Specifications and Application Considerations
    PDF 270 KB an520 1998年11月20日
    AI 生成的摘要: Adding a pull-up resistor from CMOS inputs to +5V is essential when interfacing TTL outputs with CMOS inputs to improve interchangeability, noise immunity, compatibility, and reliability. A 2kΩ resistor is generally sufficient. CMOS inputs are compatible with CMOS logic at 5V to 15V without pull-ups. Mechanical switches require pull-up or pull-down resistors to prevent noise and contact issues. Renesas disclaims liability for misuse and emphasizes adherence to product specifications and legal regulations.
