MAX4638EUE+

MAX4638EUE+ Description

The MAX4638EUE+ from Analog Devices Inc./Maxim Integrated is a high-performance, low-voltage 8:1 analog multiplexer/demultiplexer designed for precision signal routing in demanding applications. Housed in a compact 16-pin TSSOP package, this IC features an ultra-low on-state resistance (Ron) of 3.5Ω (max) and minimal channel-to-channel matching (ΔRon = 100mΩ), ensuring consistent signal integrity. It operates over a single-supply voltage range of 1.8V to 5.5V or dual-supply ±2.5V, making it versatile for mixed-voltage systems. With a -3dB bandwidth of 50MHz and fast switching times (Ton = 18ns, Toff = 7ns), it excels in high-speed signal switching.

MAX4638EUE+ Features

• Low Leakage Current: 250pA (max) ensures minimal signal distortion in precision applications.
• Low Charge Injection: 13pC reduces glitches during switching, critical for data acquisition systems.
• Low Capacitance: CS(off) = 9pF, CD(off) = 40pF minimizes crosstalk and preserves signal fidelity.
• Wide Supply Range: Supports 1.8V to 5.5V (single) or ±2.5V (dual), ideal for portable and industrial designs.
• High Bandwidth: 50MHz enables use in video, audio, and RF signal routing.
• Robust Packaging: MSL1 (Unlimited) rating ensures reliability in harsh environments.
• RoHS3 Compliant: Meets environmental standards for lead-free manufacturing.
