The MAX473EPA from Maxim Integrated is a high-performance, quad single-pole single-throw (SPST) analog switch that is designed to provide precision signal switching with minimal distortion and high speed. This device is well-suited for applications that require accurate and reliable switching of analog signals in systems such as data acquisition, audio signal routing, and industrial automation.

This analog switch operates from a single +15V to +30V supply, or from dual ±15V supplies, making it versatile for different circuit configurations. The MAX473EPA features low on-resistance (R_ON) of 100 ohms max, which is matched between switches to within 5 ohms max and remains flat over the specified signal range (0.5 ohms max). This ensures consistent performance across all switches and throughout the signal range.

With an off-leakage current of only 20pA at +25°C, the MAX473EPA offers excellent switch isolation, preventing signal bleed-through in the off state. The device also boasts fast switching speeds with transition times (t_ON / t_OFF) of 175ns/145ns max, allowing for rapid signal changes without significant delays.

The MAX473EPA comes in a compact 8-pin DIP package, which is conducive to space-constrained applications. Additionally, its extended temperature range from -40°C to +85°C ensures reliable operation in a wide range of environmental conditions. The device's ESD protection exceeds 2000V per Method 3015.7, providing robustness against electrostatic discharges that can occur during handling or operation.

Maxim Integrated's MAX473EPA is an ideal choice for designers looking for a reliable and precise analog switch that can handle multiple signal paths without compromising signal integrity. Its combination of low on-resistance, low leakage current, fast switching speeds, and ESD protection makes it a strong candidate for many analog switching applications.
