The AD8112JSTZ is a special purpose analog switch designed to provide flexible signal routing for fractional-N and integer-N low noise PLL applications. The AD8112JSTZ offers low on-resistance, fast switching speed and low quiescent power within a small package form to provide easy integration, even in space constrained applications.

The AD8112JSTZ is a single-pole double-throw (SPDT) analog switch that measures just 1.6 mm x 1.6 mm in size. This switch has a low on-resistance (RON) of 0.2 ohms maximum and low quiescent supply current (Idd) of 140 µA maximum. Additionally, the AD8112JSTZ can be operated either in the single-pole double-throw (SPDT) configuration or in the single-pole single-throw (SPST) configuration. It also features a low charge injection of 300 pC maximum, which helps reduce noise in fractional-N frequency synthesis designs.

In terms of switching speed, the AD8112JSTZ has a fast transition time of 3 μs maximum, ensuring that conversion between input and output signals is fast and efficient. This switching speed makes it well suited for high frequency applications, especially those that require transmit and receive signal routing from multiple sources.

The AD8112JSTZ is a versatile analog switch that can be used for many different applications. In the PLL design, for example, the AD8112JSTZ can be used as an input switch to route the reference clock between the fractional-N divider and the reference divider. It can also be used as an output switch to route the synthesized clock to the phase detector, loop filter and/or analog phase shifters. It can even be used as a digital control switch to enable and disable the fractional-N and reference dividers.

The AD8112JSTZ has a wide voltage range of 2.7V to 5.5V, making it suitable for both 5V and 3V applications. It is designed for operation over temperature ranges from –40°C to +85°C and exhibits good ESD protection characteristics for applications in many harsh environments.

Overall, the AD8112JSTZ is an ideal solution for any application that requires low power, fast switching speeds, and excellent signal routing. With its low on-resistance, low quiescent power, and small package size, the AD8112JSTZ is a great choice for space constrained applications that require high performance analog switching.
