Overview
The NLAS4783MN1R2G is a low-voltage analog switch manufactured by onsemi, housed in a 16-QFN (3x3 mm) package. It integrates three single-pole double-throw (SPDT) circuits with a 2:1 multiplexer configuration. The device operates within a supply voltage range of 1.65 V to 4.5 V and features a maximum on-resistance of 1 Ω. Key electrical parameters include a typical bandwidth of 17 MHz, charge injection of 50 pC, and off-channel capacitance of 5 pF. Switching times are specified at 27 ns for turn-on and 20 ns for turn-off. The component supports surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates three independent SPDT switches within a compact footprint
- Supports low-voltage operation down to 1.65 V for portable applications
- Provides high isolation with -62 dB crosstalk at 100 kHz
- Features low charge injection for accurate signal integrity
Applications
- Portable multimedia devices requiring signal routing
- Battery-powered equipment with strict power constraints
- Audio and video signal switching circuits
Procurement Notes
Verify the specific ordering suffix to ensure correct packaging format, as the part is available in both tape-and-reel and cut-tape configurations. Confirm that the 16-QFN pinout matches the target PCB layout design. Check current availability status, as distribution channels may list this component as obsolete or limited stock depending on regional inventory levels.
Selection Notes
Select this component when designing circuits that require multiple SPDT switching functions in a minimal space. Ensure the system supply voltage remains within the 1.65 V to 4.5 V operational window. Consider the 1 Ω on-resistance impact on signal attenuation if driving high-impedance loads. Verify thermal management requirements, although power dissipation is typically low in this application class.
Part Context
This device belongs to onsemi's NLAS series of low-voltage analog switches. It is designed to replace older discrete switching solutions or larger multiplexers in modern consumer electronics. The 16-QFN package allows for automated surface-mount assembly, supporting high-volume manufacturing processes common in mobile and handheld device production.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official cross-reference tools or contact the manufacturer directly for validated alternatives.
