Maxim Integrated's DG412CY+T Precision Analog Switches

The DG412CY+T from Maxim Integrated is a high-performance, monolithic, quad, single-pole single-throw (SPST) analog switch designed to provide precision and reliability in a wide range of applications. This device is part of a family of CMOS analog ICs that feature low on-resistance and low off-leakage current, making them ideal for battery-powered and portable equipment.

Constructed with Maxim's proprietary silicon-gate process, the DG412CY+T offers an excellent combination of low power consumption and high switching speed. The switch conducts equally well in both directions when on and blocks up to the power supply level when off. This versatility makes it suitable for multiplexing and signal routing applications where a bidirectional analog signal flow is required.

The DG412CY+T operates from a single +10V to +30V power supply or from dual ±4.5V to ±20V supplies. The device features an on-resistance of 100 ohms max, which is matched between switches to 5 ohms max and is flat (0.4 ohms max) over the specified signal range. With an off-leakage current of only 500pA at +25°C, the DG412CY+T ensures minimal signal loss and is highly efficient in conserving power.

Additional features of the DG412CY+T include fast switching times with tON of 175ns and tOFF of 145ns, making it suitable for high-speed applications. The device also has a low charge injection of 10pC max, which helps in maintaining signal fidelity by reducing switching transients. TTL and CMOS logic compatibility is provided, allowing the DG412CY+T to interface with a broad range of control signal levels.

Available in a compact 16-pin SOIC package, the DG412CY+T is specified over the extended -40°C to +85°C temperature range. With its robust design and high-quality performance, the DG412CY+T is an excellent choice for designers looking for a reliable solution in applications such as data acquisition systems, communication systems, test equipment, and audio signal routing.
