The device provides low-distortion on-off signals with low-voltage analog signals, enabling high levels of noise immunity in new products with demanding operating conditions. With its low power consumption, tiny package size, and pin compatible operation mode, the MAX4903EBL+ makes it possible to improve demand for small, low-power analog switches.

Applications for MAX4903EBL+

The MAX4903EBL+ is designed for applications where very low-voltage signals need to be switched from one point to another. It is suitable for applications such as cell phones, digital cameras, and wireless headsets. It is also suitable for devices requiring low distortion of signals, low power consumption, and small package sizes. Examples of such devices are video line drivers, digital-to-analog converters, digital spread spectrum receivers and other low-voltage applications.

Maximizing Device Performance

The MAX4903EBL+ features a wide range of features to maximize performance. The switch is designed to have a low off-resistance (RON) and latency, thereby providing very low distortion on-off signals with low-voltage analog signals. In addition, the device has an on-resistance (RON) of 10 ohms, further improving signal distortion. Additionally, the device has a uniquely low power consumption of 6.7 mW and a very small package size.

Operating Principle of MAX4903EBL+

The device’s operating principle is based on the principles of complementary Metal Oxide Semiconductor (CMOS) analog switches. The switch utilizes two series transistors, an n-channel and a p-channel, connected between the signal lines. An n-channel transistor is used to switch a signal low, while a p-channel transistor is used to switch a signal high. By using the two transistors in tandem, a low-power signal can be switched on or off with very low latency.
