Analog Devices Inc. ADG408BN Multiplexer

The ADG408BN from Analog Devices Inc. is a high-performance, monolithic CMOS analog multiplexer. This device is part of the ADG408 series and comes in a PDIP (Plastic Dual In-line Package) with 16 pins. It is designed to connect one of eight inputs to a common output, as determined by the 3-bit binary address lines A0, A1, and A2.

The ADG408BN features a low on resistance (R<sub>ON) of typically 80 ohms, which is nearly constant over the full analog input range. This ensures excellent linearity and low signal distortion, making it an ideal choice for precision data acquisition and control systems. The device also boasts low R<sub>ON matching between channels and flat R<sub>ON over the specified signal range, contributing to its high performance.

With a single 15 V power supply, the ADG408BN is capable of operating over a ±5 V dual supply range, providing the flexibility needed for a wide array of applications. The device also features fast switching times and low power dissipation, which are critical for power-sensitive designs. Break-before-make switching action protects against momentary crosstalk during switching, an important consideration in multiplexing applications.

Additionally, the ADG408BN has an inherent low charge injection, which minimizes the impact on signal integrity during the switching process. This characteristic, along with a high ESD (Electrostatic Discharge) rating, ensures the reliability and robustness of the device in challenging environments.

In terms of applications, the ADG408BN is suitable for use in test equipment, data acquisition systems, battery-powered systems, and communication systems, among others. Its versatility and high performance make it a dependable choice for engineers and designers looking to implement an 8-channel multiplexer in their circuits.

For detailed specifications and application guidance, designers should consult the datasheet and technical resources provided by Analog Devices Inc. The ADG408BN represents a blend of innovative design, quality manufacturing, and precision performance, typical of products from a leading semiconductor manufacturer.
