Description

The DG408D is an improved 8-channel single-ended analog multiplexer, or it can be used as a dual 4-channel differential multiplexer. It is designed using CMOS technology, which provides low power consumption and high switching speed. This IC is ideal for applications where multiple analog signals need to be selected and routed to a single output, such as in data acquisition systems, instrumentation, and audio signal routing.

Features

  • 8-Channel Single-Ended or Dual 4-Channel Configuration: Flexible configuration allows for a variety of analog signal routing needs.
  • Low On-Resistance: The IC features low on-resistance (typically 100 ohms), which minimizes signal distortion and ensures high signal integrity.
  • High Switching Speed: Fast switching times (turn-on and turn-off times) make it suitable for high-speed applications.
  • Low Power Consumption: CMOS technology ensures low power consumption, making it ideal for battery-powered devices.
  • Wide Operating Voltage Range: Can operate over a wide voltage range, typically from ±5V to ±20V for dual supply or 5V to 15V for single supply.
  • Low Charge Injection: Minimizes transients during switching, maintaining signal quality.
  • TTL/CMOS Compatible Control Inputs: Control logic is compatible with standard TTL or CMOS logic levels, simplifying interfacing.
  • Break-Before-Make Switching: Prevents short circuits by ensuring that one switch is off before another is turned on.
  • Improved ESD Protection: Enhanced protection against electrostatic discharge (ESD) increases reliability in harsh environments.
  • Small Package: Available in a 16-pin SOIC (D suffix) package for surface-mount applications.

Specifications

  • Supply Voltage:
    • Dual Supply: ±5V to ±20V
    • Single Supply: 5V to 15V
  • On-Resistance: Typically 100 ohms
  • Off Leakage Current: Typically in the picoampere range, minimizing signal leakage when the switch is off.
  • Channel Capacitance: Low capacitance (typically 5 pF), ensuring minimal signal degradation.
  • Control Logic:
    • Logic High: 2.4V minimum (for TTL logic)
    • Logic Low: 0.8V maximum
  • Switching Time: Turn-on time typically 120 ns, turn-off time typically 100 ns.
  • Operating Temperature Range: -40°C to +85°C (industrial grade)
  • Package: 16-pin SOIC (DG408DY) or other variants depending on specific requirements.

Applications

  • Data Acquisition Systems: Ideal for selecting and routing analog signals to a single ADC input.
  • Instrumentation: Used in oscilloscopes, signal analyzers, and other measurement equipment.
  • Audio Signal Routing: Suitable for switching audio signals in mixers, synthesizers, and other audio devices.
  • Medical Equipment: Used in applications like patient monitoring systems where multiple sensor signals need to be selected.
  • Communication Systems: For routing RF or IF signals in communication equipment.
  • Automation Systems: Used in process control and automation equipment for signal routing and selection.
