Analog Devices' ADG1412L is a monolithic complementary metal-oxide semiconductor (CMOS) device that contains four independently selectable switches designed on an iCMOS® process. The industrial CMOS (iCMOS) modular manufacturing process combines high-voltage CMOS and bipolar technologies to create a highly efficient switch. The ADG1412L switch offers excellent linearity and low distortion (1.5 Ω typical) due to its flat on-resistance (RON) profile over the full analog input range when switching signals.
The ADG1412L contains four independent single-pole single-throw (SPST) switches that turn on with Logic 1. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the supplies. When off, signal levels to the supplies are blocked, ensuring a clean signal path. An external VL supply provides flexibility for lower logic control. The ADG1412L is both 1.2 V and 1.8 V JEDEC standard compliant, making it compatible with a wide range of devices.
To evaluate the performance of the ADG1412L, Analog Devices provides the EVAL-ADG1412LEBZ evaluation board. This board allows for easy testing and characterization of the switch's performance in various applications.
In summary, Analog Devices' ADG1412L quad SPST switch is a highly efficient switch designed for precise signal switching. Its excellent linearity and low distortion (1.5 Ω typical) make it an ideal choice for applications where signal integrity is critical. With four independent switches, compatibility with a wide range of devices, and easy evaluation using the EVAL-ADG1412LEBZ board, the ADG1412L offers a comprehensive solution for high-quality signal switching.
