The MAX4581ASE+ is an analog switch, multiplexer and demultiplexer suitable for applications requiring low charge-injection and fast switching speeds. The devices operate from –40°C to +85°C and come in two small sizes, 8-pin SOIC, 8-pin TSSOP, and 8-pin narrow SOIC packages.The MAX4581ASE+s offers low charge-injection operation and low power consumption, and it features an enable line that is shared by all channels, making the analog switch easy to enable and disable.The MAX4581ASE+ offers a wide voltage range of ±15V digital inputs with a 2.5V to 5V logic compatibility. The low charge-injection operation minimizes audible noise for audio applications and reduces the total harmonic distortion for video applications.The MAX4581ASE+ has fast switching speeds of 15ns (max). This makes it ideal for applications that require low-noise switching and fast settling. The device also offers excellent isolation performance which makes it suitable for use in high-impedance signal-chain applications.To maximize its efficiency, the MAX4581ASE+ has a low power supply current of 1uA (max). This means that the device won’t require large current draw from the system.The MAX4581ASE+ also features thermal shutdown with hysteresis and internal ESD protection. This helps protect the device in case of power surges or other potentially damaging events.The MAX4581ASE+’s application field includes audio and video switching, signal routing, signal sampling, signal mixing, and distortion correction. It can also be used in data acquisition systems, instrumentation, medical instruments, and portable systems.The MAX4581ASE+ works by using a single-pole, double-throw switching element with two independently controlled digital input pins (pin 4 and 5). The signal is routed from an input pin to one of several output pins (pins 2, 3, 6, and 7). The common input signal is switched to either one of the two output pins indicated by the logic level of the two digital input pins (pin 4 and 5). The MAX4581ASE+ provides high-level isolation between the input signal and output signal by using an optical isolation technique. This ensures that no signal loss occurs and that there is no crosstalk between the two signal lines.In summary, the MAX4581ASE+ is a versatile analog switch, multiplexer, and demultiplexer suitable for audio and video switching, signal routing, signal sampling, signal mixing, and distortion correction applications. Its low power consumption makes it ideal for portable systems and general-purpose applications. Its integrated ESD protection and thermal shutdown safeguards ensure reliability and proper operation.
