MAX4712CUE+

The MAX4712CUE+ is a high-performance analog multiplexer/demultiplexer. It is primarily used in analog signal measurement and switching applications, but can also be used for other applications such as data acquisition, signal conditioning, and analog-to-digital conversion. This part is an excellent choice for applications that require high-speed performance, accuracy, and signal integrity. The MAX4712CUE+ can switch and sample analog signals in a wide range of frequencies up to 18MHz. The part features low ON-resistance and excellent signal-to-noise performance.

The MAX4712CUE+ is a very versatile device. The multiplexer/demultiplexer can be configured in two different operating modes. In the single-ended mode, up to four input signals can be switched single-ended at a rate of 1.6MHz. In the differential mode, two differential input signals can be switched differential at a rate of 18MHz. This allows the device to be used in a wide variety of applications, with the ability to switch either single-ended or differential signals.

The MAX4712CUE+ is designed to operate from a single power supply, typically 5V. The power supply and the signal ground should be separated for optimum performance. The part has a maximum-common-mode voltage range of ±2.0V. When the power is applied, the part has a low leakage current. This ensures low power consumption and extends battery life in portable applications.

The MAX4712CUE+ has an adjustable control voltage input (VCOM) that can be used to compensate for changes in the ON state resistance due to temperature or power supply variations. The control voltage can be adjusted to achieve a tight output impedance match across the full frequency range. This ensures signal integrity and helps minimize signal reflections, which can lead to errors in measurements and signal processing.

The device can be operated in two different operating states. In the bistable mode, the device is configured to maintain the latest switch states when the input control voltage is disconnected. In the “nA” mode, the device will enter the N-channel MOSFET OFF state when the input control voltage is removed. This ensures that the signal will not leak, even when the device is not actively switching.

The MAX4712CUE+ features both high signal-to-noise performance and high immunity to noise and transients. The device features an ESD (electro-static discharge) protection of at least 2 kV HBM (human body model). This helps prevent system damage from ESD voltages. The MAX4712CUE+ features extensive self-testing features that ensure high reliability and self-diagnostic capabilities.

The MAX4712CUE+ provides an efficient way to switch and sample analog signals. It is suitable for a wide range of applications, from signal conditioning to data acquisition. Its low leakage current, high ESD protection, and self-diagnostic capabilities make it an ideal choice for any application requiring high performance and signal integrity.
