Maxim Integrated's MAX391CSE+T: Precision, Quad, SPST Analog Switches

The MAX391CSE+T from Maxim Integrated is a high-performance, quad, single-pole single-throw (SPST) analog switch that offers precision switching capabilities for a wide range of applications. This robust component is designed to operate with a single +5V supply or dual ±5V supplies, making it versatile for both unipolar and bipolar operations.

With its low on-resistance (R_ON) of just 100Ω (max) and R_ON matching between channels of 5Ω (max), the MAX391CSE+T ensures minimal signal distortion and excellent channel-to-channel uniformity. This is particularly important in applications that require precise signal routing and high integrity, such as data acquisition systems, test equipment, and audio signal switching.

The device also boasts a low charge injection of 10pC (max), which minimizes the transient disturbance in the signal path when switching. Additionally, it features fast switching times (t_ON = 175ns max, t_OFF = 145ns max) to support applications that require quick response times.

The MAX391CSE+T includes an important feature for power-sensitive applications: its low power consumption. With a quiescent current of just 0.1µA (max), this analog switch helps conserve power in portable and battery-operated devices. Furthermore, the device is TTL/CMOS-logic compatible, allowing for easy integration with digital control interfaces.

For enhanced reliability, the MAX391CSE+T is specified for the extended industrial temperature range of -40°C to +85°C. It is available in a 16-pin narrow SO package, which is suitable for space-constrained applications. This product is also lead-free and RoHS compliant, adhering to current environmental standards.

Whether used in communication systems, portable instruments, or computer peripherals, the MAX391CSE+T from Maxim Integrated offers a combination of precision, low power consumption, and high reliability, making it an excellent choice for designers seeking a high-quality analog switching solution.
