DG401_DG403 Functional Diagram
Description
The DG401 and DG403 monolithic CMOS analog switches have TTL and CMOS compatible digital inputs. These switches feature low analog ON resistance (45Ω) and fast switch time (tON150ns). Low charge injection simplifies sample and hold applications. The improvements in the DG401, DG403 series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling 30VP-P signals. Power supplies may be single-ended from +5V to +34V, or split from ±5V to ±17V. The analog switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with analog signals is quite low over a ±15V analog input range. The three different devices provide the equivalent of two SPST (DG401) or two SPDT (DG403) relay switch contacts with CMOS or TTL level activation. The pinout is similar, permitting a standard layout to be used, choosing the switch function as needed.

- 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.
- Application NotePDF 468 KB an557 May 24, 2002AI-generated Summary: 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.
- Application NotePDF 300 KB an1034 Nov 20, 1998AI-generated Summary: 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.
- Application NotePDF 302 KB an1033 Nov 20, 1998AI-generated Summary: A CMOS multiplexer (MUX) can function as a demultiplexer by using synchronized address lines and capacitors to hold output signals between samples. However, overvoltage protection requires an external network. More precise demultiplexing uses sample-and-hold circuits like the HA-2420/2425 for each channel. The document also includes detailed disclaimers about product use, liability, quality grades, safety responsibilities, and regulatory compliance for Renesas Electronics products.
- Application NotePDF 270 KB an520 Nov 20, 1998AI-generated Summary: 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.
