Analog Devices Inc. ADG442BN Product Overview

The ADG442BN from Analog Devices Inc. is a high-performance, monolithic CMOS device comprising four independently selectable single-pole, double-throw (SPDT) switches. This precision analog switching device is designed to provide superior switching performance for a wide range of applications, including data acquisition systems, communication systems, and process control environments.

With its low power consumption and wide dual supply voltage range of ±4.5 V to ±18 V, the ADG442BN is an ideal choice for battery-powered and portable instruments. Additionally, its single supply operation from 9 V to 36 V provides flexibility for various circuit designs. The device features an on-resistance profile that is very flat over the full analog input range, ensuring excellent linearity and low distortion when passing analog signals.

Key Features of ADG442BN

• Low On-Resistance: The switch offers a low on-resistance of typically 45 Ω, which remains consistent over the full signal range.
• High Switching Speed: Fast transition times with a t<sub>ON of typically 175 ns and t<sub>OFF of typically 145 ns allow for efficient signal routing.
• Low Power Consumption: The device exhibits a low power dissipation, minimizing the impact on battery life in portable applications.
• Wide Operating Temperature Range: The ADG442BN operates reliably over an extended industrial temperature range from -40°C to +85°C, suitable for harsh environments.
• Bidirectional Signal Flow: Signals can flow in both directions through the switch, providing design flexibility.
• Improved Off Isolation: The device ensures high isolation of the signal in the off-state, reducing potential interference.
• ESD Protection: It includes enhanced electrostatic discharge (ESD) protection, safeguarding the device from static damage during handling and operation.

The ADG442BN is available in a 16-lead PDIP package, which is robust and easy to integrate into a variety of circuit boards. Its latch-up performance exceeds 100 mA per JESD78, Class II, ensuring stability and reliability in use.

Whether you are designing precision filters, data acquisition systems, or need a reliable switch for multiplexing signals, the ADG442BN from Analog Devices Inc. offers a blend of performance and durability that can meet the stringent requirements of your application.
