The MAX321CUA+T is a precision, dual, high-speed analog switch from Maxim Integrated designed to operate with single +5V to +30V supplies or dual ±4.5V to ±20V supplies. This versatile component is engineered to offer low on-resistance and on-resistance matching, making it an excellent choice for applications requiring minimal signal distortion and consistent performance.

Key Features

• Low On-Resistance: Typically 35Ω at +25°C, which ensures minimal signal loss and low I/O impedance.
• Low Crosstalk: -90dB at 1MHz, which minimizes interference between switch channels and preserves signal integrity.
• High Off-Isolation: -83dB at 1MHz, which prevents signal leakage between the open switch and any active signal lines.
• Fast Switching Times: t_ON is 175ns and t_OFF is 145ns, making the MAX321CUA+T suitable for high-speed applications.
• Single-Supply Operation: Can operate from a single supply voltage, offering design flexibility for various systems.
• Dual-Supply Operation: Also supports dual supply voltages for applications requiring bipolar operating ranges.
• Low Power Consumption: Ensures energy efficiency, which is critical for battery-powered and energy-sensitive devices.
• TTL/CMOS-Compatible: Compatible with most logic families, allowing easy integration into digital systems.

Applications

The MAX321CUA+T is suitable for a wide range of applications, including:

• Audio and Video Signal Routing
