ADG452BN

The ADG452BN from Analog Devices is a high-performance monolithic CMOS analog switch designed for a wide range of applications. It comprises four independently selectable single-pole/single-throw (SPST) switches, each capable of conducting equally well in both directions when on. This device is built on an enhanced LC2MOS process, providing low power dissipation alongside high switching speed and a low on-resistance of typically 5 Ohms.

The on-resistance profile is notably flat across the full analog input range, ensuring excellent linearity and minimal distortion, making it suitable for audio and video signal switching. With fast switching times (tON typically 70 ns, tOFF typically 60 ns) and a high signal bandwidth, the ADG452BN is well-suited for applications requiring rapid signal changes.

Designed for versatility, the ADG452BN operates with supply voltages up to ±4.5V to ±20V and handles analog signal ranges up to ±15V. Its ultralow power dissipation (18 μW typical) makes it an excellent choice for battery-powered and portable instruments. The device is specified for operation over a temperature range of -40°C to 85°C.

Packaged in a 16-pin PDIP through-hole configuration, the ADG452BN is designed for easy integration into existing circuit designs. Its features include low charge injection (20 pC) and low crosstalk (-90 dB at 1MHz), contributing to signal integrity in demanding applications like automatic test equipment, precision data acquisition, and communication systems.
