MAX9656AE+ Application Field and Working Principle

The MAX9656AE+ from Maxim Integrated is a small-footprint, low-power, advanced-capability analog switch designed for use in a variety of applications. The device features configurable switching logic and an adjustable supply voltage up to 24V, making it suitable for use in battery-powered and high-voltage systems. The MAX9656AE+ also includes configurable open/closed loop gain, voltage and transient performance, making it an ideal choice for high-precision and demanding switching applications.

Overview

The MAX9656AE+ is a precision analog switch designed to provide high-speed operation in short-period switching applications. It is an ideal choice for systems that require switchable analog lines, high-speed switching, and improved signal-to-noise ratio. With low switch-on resistance (RON) and high off-state resistance (ROFF), as well as a high maximum tolerated input/output voltages of 24V and 36V, respectively, the MAX9656AE+ can handle a wide range of signals. The switch-on and switch-off times are fast, meaning switching times are not an issue, no matter how soon an application needs to switch. The device\'s low power consumption—down to 6µA—and low profile package make it a great choice for mobile and space-constrained applications. In addition, the MAX9656AE+ is designed to handle bus contention, allowing for reliable and deterministic communication.

Architecture

At the heart of the MAX9656AE+ is its switching backend, which consists of multiple single-pole, double-throw (SPDT) analog switches. Each switch employs a specialized open-drain structure in which one terminal is connected to the switch on terminal, one to the switch off terminal, and one to the output terminal. When the switch is on, the voltage of the output terminal is controlled by a configurable logic level. When the switch is off, the output terminal is pulled to ground. This configuration provides a high-impedance "on" state and low-impedance "off" state, making it an ideal choice for high-speed transients.

Operation

The MAX9656AE+ features a flexible switching logic and adjustable supply voltage. The switch-on and switch-off times can be set to optimize system performance. The MAX9656AE+ can be programmed to either parallel or serial mode. In parallel mode, all switches are turned on or off simultaneously, minimizing delay, which is useful for fast transient switching. In serial mode, the switch delay is automatically adjusted to match the logic level of the logic signal. There are four logic states: high logic active, low logic active, active low logic active, and active high logic active. The logic level of each logic state can be independently set.

Performance

The MAX9656AE+ delivers excellent switching performance. With its high-precision control of switch-on and switch-off times and low leakage current, the device provides reliable and reliable transient performance. The low power consumption (6µA) makes the MAX9656AE+ a great choice for mobile and battery-powered applications. Additionally, the device features configurable open/closed loop gain, making it ideal for signal processing applications.

Conclusion

The MAX9656AE+ from Maxim Integrated is a versatile, small-footprint, low-power analog switch designed for a host of applications. Its configurable switch-on and switch-off times and adjustable supply voltage make it ideal for high-speed switching applications. In addition, its small form factor and low power consumption make it a great choice for mobile and battery-powered applications. With its configurable logic and open/closed loop gain, the MAX9656AE+ is the perfect choice for demanding switching applications.
