The MAX4690EWE+ from Maxim Integrated is a high-performance, low-voltage, quad SPST (single-pole single-throw) analog switch designed to deliver precision and reliability for a broad range of applications. Its compact and efficient design makes it an ideal choice for portable and space-constrained applications.

Key Features

• Low Voltage Operation: The MAX4690EWE+ operates at a single +1.8V to +5.5V supply, making it suitable for battery-powered devices and low-voltage systems.
• Low On-Resistance: It features low on-resistance (R<sub>ON), typically 100 ohms at +5V, which minimizes signal distortion and ensures efficient signal transmission.
• High Off-Isolation: The device provides excellent off-isolation at -50dB at 1MHz, thereby reducing signal crosstalk between channels when switches are in the off state.
• High Bandwidth: With a high bandwidth (200MHz), the MAX4690EWE+ can handle a wide range of frequencies, making it versatile for various signal-switching applications.
• Low Crosstalk: At -86dB at 1MHz, the low crosstalk characteristic of this switch ensures minimal interference between channels during operation.
• Fast Switching Times: The device boasts fast switching times (t<sub>ON = 25ns and t<sub>OFF = 20ns), enabling quick transitions and suitable for high-speed applications.
• ESD Protection: It includes ESD protection diodes to the V+ supply, which enhances the robustness of the device against electrostatic discharges.
