Maxim Integrated Product Overview: MAX379CWG+

The MAX379CWG+ from Maxim Integrated is a precision, dual, SPST (Single Pole Single Throw) analog switch that offers low on-resistance and low leakage currents. This component is designed to operate from a single +2V to +12V supply or from dual ±2V to ±6V supplies, making it versatile for a wide range of applications, including battery-powered devices.

Featuring a max on-resistance of just 35Ω and a max on-resistance match between channels of 2Ω, the MAX379CWG+ ensures minimal signal distortion and excellent channel-to-channel uniformity. The low on-resistance is flat (0.5Ω max) over the specified signal range, which extends from the negative supply rail to within 1.5V of the positive supply. This characteristic is essential for maintaining signal integrity in applications that require a wide dynamic range.

The device also boasts a low charge injection of 10pC (max) and low power consumption, with a supply current of only 0.1µA (max), further enhancing its suitability for power-sensitive applications. Additionally, the MAX379CWG+ has an ESD tolerance of ±2000V, providing robust protection against electrostatic discharge events.

With its fast switching times (tON 150ns max, tOFF 100ns max), the MAX379CWG+ is well-suited for sample-and-hold circuits, battery-operated equipment, audio and video signal routing, and communication systems. Its high off-isolation of -65dB at 1MHz ensures that signals are effectively isolated when the switch is in the off state, minimizing crosstalk and noise interference between channels.

The MAX379CWG+ comes in a 16-pin wide SO package and is specified over the extended -40°C to +85°C temperature range. Its reliability and performance make it a top choice for designers who require a high-quality analog switch for their precision applications.

Overall, the MAX379CWG+ represents Maxim Integrated's commitment to providing high-performance integrated circuits that meet the stringent requirements of modern electronic systems.
