ISL43681IRZ is an integrated analog switch which belongs to the Interface - Analog Switches, Multiplexers, Demultiplexers category. It offers a wide range of features that enable designers to use it in an ever-expanding list of applications.

The ISL43681IRZ offers single pole double throw (SPDT) switching combined with high-efficiency low power CMOS logic control. These features make it suitable for applications requiring low-power, high-speed switching of analog signals across a range of frequencies and signal levels.

The ISL43681IRZ provides a wide input voltage range from 4.5V to 30V, allowing it to be used in a number of different applications. It also has an adjustable input resistance between 3.2K and 100K. This feature ensures that the input signal is not distorted or clipped, preventing signal degradation when switching between inputs. This versatile switch also includes a logic input signal filter in order to reduce EMI noise during switching. All of these features result in a low total harmonic distortion (THD) and high common-mode rejection ratio (CMRR), making it suitable for use in audio applications.

The high level of integration equips the ISL43681IRZ with high-speed switching capabilities. When set to on-state, the switch reaches a low on resistance of 350mΩ in as little as 50ns, which is ideal for applications requiring speed. When set to off-state, the switch can reach a high off resistance of 10GΩ in as little as 300ns.

The ISL43681IRZ also features a high-speed low delay voltage follower to ease the fast switching process of signals across different sources. The voltage follower helps ensure that the input signal is read at its input resistance and then passed to the output at the resistor’s desired wattage. This helps minimize signal distortion and prevents cross-talk between adjacent channels.

The ISL43681IRZ is an ideal solution for applications requiring high-efficiency, low power, and high-speed switching of analog signals. It is particularly suitable for audio applications as it has a low total harmonic distortion (THD) and high common-mode rejection ratio (CMRR).

The ISL43681IRZ is a versatile solution which offers the flexibility designers need in developing applications ranging from consumer audio equipment to communication and power management systems.
