Description

The DG508 is a CMOS analog multiplexer that features 8 channels. It allows the connection of one of eight single-ended input signals to a common output or a common input to one of eight outputs. The IC is designed with low on-resistance and low leakage current, which makes it ideal for applications requiring high signal integrity. It is commonly used in data acquisition systems, instrumentation, and various signal routing tasks.

Features

  • 8-Channel Multiplexer: Can connect one of eight input channels to a common output, making it suitable for applications requiring the selection of multiple signals.
  • Low On-Resistance: Features low on-resistance (typically around 100 ohms), ensuring minimal signal distortion and attenuation.
  • Low Leakage Current: Designed with low off-state leakage currents, typically in the picoampere range, which helps maintain signal quality.
  • Wide Supply Voltage Range: Operates over a wide range of supply voltages, typically ±5V to ±20V for dual supply or 5V to 20V for single supply.
  • TTL/CMOS Compatible Logic Inputs: Control logic inputs are compatible with standard TTL and CMOS logic levels, allowing easy interfacing with digital circuits.
  • Break-Before-Make Switching: Prevents short circuits by ensuring that one channel is fully disconnected before another is connected.
  • High Signal Bandwidth: Capable of handling high-frequency signals, making it suitable for a range of analog signal types.
  • Low Power Consumption: CMOS technology ensures that the IC operates with minimal power consumption, ideal for battery-operated devices.
  • Improved ESD Protection: Enhanced ESD protection increases reliability in various operating environments.

Specifications

  • Supply Voltage:
    • Dual Supply: ±5V to ±20V
    • Single Supply: 5V to 20V
