Overview
The NLAS3899BMNTWG is a dual analog switch IC manufactured by onsemi, featuring two double-pole double-throw (DPDT) channels within a single package. It operates on a single supply voltage ranging from 1.65V to 4.3V. The device exhibits a maximum on-resistance of 2.5 ohms and a channel-to-channel matching of 700 milliohms. Electrical performance includes a -3dB bandwidth of 280MHz, with turn-on and turn-off times of 40ns and 30ns respectively. Charge injection is specified at 111pC, while leakage current remains below 300nA. The component is housed in a 16-QFN (3x3mm) surface-mount package and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Dual DPDT configuration providing two independent switching paths in a compact footprint
- Low on-resistance of 2.5 ohms ensures minimal signal attenuation across the passband
- High-speed switching capability with nanosecond-level transition times for dynamic applications
- Wide single-supply voltage compatibility supporting low-power portable systems
Applications
- Signal routing in portable consumer electronics such as smartphones and tablets
- Audio path switching in mobile devices and wearable technology
- Video signal selection in display interfaces and multimedia equipment
- Test and measurement instrumentation requiring precise analog signal routing
Procurement Notes
Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as production status may affect long-term availability. Ensure packaging specifications match design requirements before ordering.
Selection Notes
Evaluate on-resistance and bandwidth requirements against target signal frequencies. Consider thermal dissipation capabilities within the 16-QFN package for high-current applications. Verify supply voltage ranges align with system power rails. Assess charge injection levels for precision analog signal integrity needs.
Part Context
This component belongs to the NLAS3899 series of low-power analog switches designed for space-constrained portable applications. The series offers various configurations optimized for audio, video, and data signal routing. The BMNTWG suffix indicates specific packaging and environmental compliance attributes defined by onsemi.
Replacement Considerations
Check for pin-compatible alternatives within the same family. Verify electrical parameter equivalence for resistance, bandwidth, and voltage ratings. Confirm package dimensions and thermal characteristics match existing board layouts.
