The MAX393AUA from Maxim Integrated is a high-performance, precision, quad, single-pole single-throw (SPST) analog switch that offers a perfect solution for precision signal switching in a wide range of applications. It is designed to operate from a single +5V supply or dual ±15V supplies, making it extremely versatile for various system designs.

This analog switch features four independently controllable switches, each with low on-resistance and on-resistance matching between channels of less than 5Ω. This ensures minimal signal distortion and excellent channel-to-channel crosstalk performance, which is critical in high-precision analog applications. The MAX393AUA also boasts low charge injection, which minimizes signal corruption during switching events, making it suitable for sample-and-hold circuits, test equipment, and audio signal routing.

Key Features:

• Low On-Resistance: 100Ω max
• On-Resistance Matching Between Channels: 5Ω max
• Low Charge Injection: 10pC max
• Single-Supply Operation: +5V
• Dual-Supply Operation: ±15V
• Fast Switching Times: t<sub>ON 175ns max, t<sub>OFF 145ns max
• Low Power Consumption
• ESD Protection: >2000V per Method 3015.7
• TTL/CMOS-Compatible Control Inputs

The MAX393AUA is available in an ultra-small, 8-pin µMAX package, which is ideal for space-constrained applications. Its extended temperature range of -40°C to +85°C allows for reliable operation in harsh environments. The device's ESD protection exceeds 2000V per Method 3015.7, providing robustness for handling and long-term reliability.

Typical applications for the MAX393AUA include data acquisition systems, communication systems, avionics, medical equipment, and any other system that requires high-precision analog signal management. With its precision specifications and reliable performance, the MAX393AUA is a smart choice for designers looking to optimize their analog signal path with minimal signal loss and distortion.
