MAX4066CSD

MAX4066CSD Description

The MAX4066CSD from Analog Devices Inc./Maxim Integrated is a high-performance, quad SPST (Single-Pole Single-Throw) analog switch designed for precision signal routing in low-voltage applications. Housed in a 14-pin SOIC package, this IC features four independent switches with a low on-state resistance (Ron) of 45Ω (max) and minimal leakage current (1nA max). Operating over a 2V to 16V supply range, it supports bidirectional signal flow and delivers a -3dB bandwidth of 100MHz, making it suitable for high-speed signal switching. Although marked as Obsolete, its robust performance and low charge injection (1pC) ensure reliability in legacy or specialized systems.

MAX4066CSD Features

• Low On-Resistance: 45Ω (max) ensures minimal signal attenuation.
• Fast Switching: Turn-on/turn-off times of 100ns/75ns for rapid signal routing.
• Low Leakage: 1nA (max) leakage current enhances signal integrity.
• High Bandwidth: 100MHz -3dB bandwidth supports high-frequency applications.
• Low Charge Injection: 1pC reduces glitches in sensitive circuits.
• Wide Voltage Range: 2V to 16V operation accommodates diverse systems.
• Channel Matching: ΔRon of 500mΩ ensures consistent performance across switches.
• Low Capacitance: 9pF (off-state) minimizes crosstalk and loading effects.

MAX4066CSD Applications

• Audio/Video Signal Routing: Ideal for multiplexing low-distortion audio/video signals.
• Test & Measurement Equipment: High bandwidth and low leakage suit precision instrumentation.
