NLAS3899BMNTXG

NLAS3899BMNTXG Description

The NLAS3899BMNTXG from onsemi is a high-performance dual-pole dual-throw (DPDT) analog switch designed for precision signal routing in low-voltage applications. Packaged in a compact 16-QFN and supplied in Tape & Reel (TR), this IC features an ultra-low on-state resistance (Ron) of 2.5Ω (max) and minimal channel-to-channel matching (ΔRon) of 700mΩ, ensuring consistent signal integrity. Operating within a 1.65V to 4.3V supply range, it supports high-speed switching with turn-on/turn-off times of 40ns/30ns (max) and delivers a -3dB bandwidth of 280MHz, making it ideal for high-frequency signal paths. Despite its obsolete status, it remains a reliable choice for legacy designs requiring low leakage (300nA max) and low charge injection (111pC).

NLAS3899BMNTXG Features

• Low Ron & High Bandwidth: 2.5Ω (max) Ron and 280MHz -3dB bandwidth minimize signal attenuation and distortion.
• Fast Switching: 40ns/30ns (Ton/Toff) enables rapid signal routing in time-critical applications.
• Low Power Operation: 1.65V–4.3V supply range suits battery-powered and portable devices.
• Minimal Crosstalk: 10pF channel capacitance (CS(off)/CD(off)) reduces interference in multiplexed systems.
• Robust Compliance: ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Compact & Reliable: 16-QFN package with MSL 1 (unlimited) moisture sensitivity ensures durability in surface-mount designs.

NLAS3899BMNTXG Applications

• Portable Electronics: Signal routing in smartphones, tablets, and wearables due to low-voltage operation.
• Test & Measurement: High-speed multiplexing in data acquisition systems and oscilloscope front-ends.
• Audio/Video Switching: Low-distortion signal paths in HDMI switches and audio interfaces.
• Industrial Control: Reliable performance in PLC I/O modules and sensor interfaces.
• Legacy System Maintenance: Suitable for repairs/upgrades of older designs requiring DPDT functionality.

Conclusion of NLAS3899BMNTXG

The NLAS3899BMNTXG excels in low-voltage, high-speed signal switching with its low Ron, fast response, and high bandwidth. While marked obsolete, its low leakage, minimal charge injection, and robust packaging make it a pragmatic choice for precision analog routing in portable, industrial, and test equipment. Engineers seeking a DPDT switch with balanced performance should consider this IC for legacy or low-power designs.
