Maxim Integrated MAX4634ETB+ High-Speed Analog Switch

The Maxim Integrated MAX4634ETB+ is a state-of-the-art, low-voltage, single-pole/double-throw (SPDT) analog switch that is designed for precision and high-speed switching applications. This compact and efficient device is a perfect solution for routing signals in a wide range of systems, from portable battery-powered devices to communication infrastructure and industrial equipment.

Operating from a single +1.8V to +5.5V power supply, the MAX4634ETB+ is ideal for both single and dual supply operations, providing designers with flexibility in various circuit configurations. Its low on-resistance (R<sub>ON) of just 4Ω (max) at +5V ensures minimal signal distortion and power loss, making it highly efficient for passing analog signals.

The device boasts a fast switching speed with a turn-on time of 25ns and a turn-off time of 20ns, which allows for quick signal routing and reduces latency in critical signal paths. Additionally, the MAX4634ETB+ offers high off-isolation of -45dB at 50MHz and crosstalk of -50dB at 50MHz, providing excellent signal integrity by minimizing noise and interference between channels.

The MAX4634ETB+ comes in a tiny 10-pin TDFN package, measuring just 3mm x 3mm, which helps to save valuable board space in compact designs. It also features an extended operating temperature range from -40°C to +85°C, ensuring reliable performance in harsh environments.

Key features of the MAX4634ETB+ include:

• Low-voltage operation from +1.8V to +5.5V
• Low on-resistance: 4Ω (max) at +5V
