Maxim Integrated MAX333ACPP+ Analog Switch

The MAX333ACPP+ from Maxim Integrated is a high-performance, quad single-pole, double-throw (SPDT) analog switch that is designed to provide precision and versatility in a wide range of applications. This device is particularly suitable for signal routing in communication systems, data acquisition equipment, and audio/video switching due to its low on-resistance and high off-isolation characteristics.

Constructed with Maxim's proprietary silicon-gate process, the MAX333ACPP+ boasts an on-resistance (R<sub>ON) of just 100 ohms max, which is matched between channels to within 5 ohms and remains flat over the specified analog signal range. This ensures minimal signal distortion and consistent performance across all switches. The device also offers low charge injection, making it ideal for precision sample-and-hold circuits and other applications where signal integrity is paramount.

The MAX333ACPP+ can operate from a single +5V supply or dual ±15V supplies, providing flexibility in various system designs. It also features fast switching times, with t<sub>ON and t<sub>OFF typically at 175ns and 145ns, respectively, allowing for efficient signal management in time-critical applications. Additionally, the device has a high off-isolation of -75dB at 1MHz, which minimizes crosstalk between channels.

For enhanced reliability, the MAX333ACPP+ includes fault protection against overvoltage up to ±40V. Even during power-off conditions, this analog switch will protect connected components from potential damage. The switch's digital inputs are TTL and CMOS logic compatible, simplifying integration with a wide range of control interfaces.

Offered in a 20-pin PDIP package, the MAX333ACPP+ is designed for ease of use in both prototyping environments and production runs. Its robust design ensures performance stability over the extended industrial temperature range of -40°C to +85°C, making it a reliable choice for demanding applications.

With its combination of low on-resistance, high-speed switching, and durable construction, the Maxim Integrated MAX333ACPP+ analog switch is an excellent choice for designers seeking a switch solution that does not compromise on performance or versatility.
