Maxim Integrated MAX4840EXT+ Ultra-Low Leakage Switch

The Maxim Integrated MAX4840EXT+ is a precision-engineered ultra-low leakage current switch designed to deliver high-performance switching solutions for a wide range of applications. This compact, single-pole/single-throw (SPST) analog switch is ideal for use in battery-powered devices, medical equipment, and other sensitive electronic systems where power efficiency and minimal leakage are of paramount importance.

Featuring an advanced CMOS technology, the MAX4840EXT+ provides an exceptionally low leakage current of only 1pA at +25°C, which helps to preserve battery life and maintain the integrity of critical signal paths. The device operates from a single +1.6V to +3.6V power supply, making it versatile for various low-voltage applications.

The MAX4840EXT+ boasts a fast switching speed, with turn-on and turn-off times typically less than 0.5µs, ensuring quick response times in circuits that require precise control. The switch's high off-isolation of -75dB at 1MHz further enhances its performance by reducing signal crosstalk when the switch is in the off position.

With its tiny 6-pin SC70 package, the MAX4840EXT+ is designed for space-constrained applications. The small footprint allows designers to save valuable board space without sacrificing functionality. Additionally, the device features an ESD protection of ±15kV Human Body Model (HBM), which provides robustness against electrostatic discharges during handling and operation.

Key features of the MAX4840EXT+ include:

• Ultra-Low Leakage Current: 1pA at +25°C
• Single +1.6V to +3.6V Supply Voltage Range
• Fast Switching: Turn-On/Turn-Off Times < 0.5µs
• High Off-Isolation: -75dB at 1MHz
• Compact 6-Pin SC70 Package
