ADG2712

The ADG2712 is an ultra-low leakage, quad-channel single-pole/ single-throw (SPST) switch. The ADG2712 is designed with a unique architecture that provides four individually controlled switch channels each with a typical on leakage current of 8pA at 85°C and 56pA at 125°C. This ultra-low leakage, coupled with low on resistance of just 9.1Ω, provides a compact switching solution for applications that demand the highest precision.The ADG2712 has a rail-to-rail input signal range. Each switch conducts equally well in both directions when on. The switches are turned on with a Logic 1 input on the corresponding digital control line and the digital control inputs are 1.8V JEDEC compliant for ease of use with microcontrollers and field programmable gate arrays (FPGAs).The ADG2712 is well suited as a solid‑state replacement for mechanical relays in precision measurement and instrumentation applications. It offers significant advantages in reliability, size, and switching speed, while maintaining the low leakage performance traditionally associated with relay‑based solutions. The device enables accurate routing of low‑level signals without disturbing high‑impedance nodes.With its low leakage characteristics and precision switching performance, the ADG2712 is ideal for use in instrumentation, data acquisition systems, and sensor interfaces—including biosensor and electrochemical measurement applications.
