Overview
The NLAST44599MNR2 is a dual DPDT analog switch IC manufactured by onsemi, housed in a 16-QFN (3x3 mm) package. It operates on a single supply voltage ranging from 2V to 5.5V. Key electrical parameters include a maximum on-resistance of 25 ohms, a -3dB bandwidth of 175MHz, and charge injection of 3pC. The device features a maximum leakage current of 1nA and offers a crosstalk rejection of -90dB at 100kHz. Switching times are specified with a maximum turn-on time of 14ns and turn-off time of 5ns. The component supports an operating temperature range from -55°C to 125°C.
Feature Summary
- Dual Double-Pole Double-Throw (DPDT) switching configuration for signal routing
- Low on-resistance of 25 ohms for minimal signal attenuation
- High bandwidth of 175MHz suitable for high-frequency applications
- Low charge injection of 3pC to preserve signal integrity
Applications
- Signal routing in portable consumer electronics
- Audio and video signal switching in multimedia devices
- Data acquisition systems requiring low distortion
- Telecommunications equipment signal path management
Procurement Notes
Verify the exact part number suffix carefully, as the 'G' designation typically indicates RoHS compliance, whereas the base model NLAST44599MNR2 may not be. Confirm availability status, as this series has been subject to discontinuation notices. Ensure the selected variant matches the required environmental and regulatory standards for the target application.
Selection Notes
Select this component when a compact dual DPDT switch is required with low on-resistance and high bandwidth. Consider the 16-QFN package constraints for PCB layout. Verify that the single-supply voltage range of 2V to 5.5V aligns with the system power rails. Check if the specific RoHS-compliant suffix is available if environmental regulations mandate it.
Part Context
This component belongs to the NLAST44 series of analog switches from onsemi. It is designed for applications requiring efficient signal routing in space-constrained environments. The series is known for combining low power consumption with high performance metrics like bandwidth and low distortion, making it suitable for modern portable electronic devices.
Replacement Considerations
Check for direct substitutes within the NLAST44 family or other dual DPDT switches from onsemi. Verify pin compatibility and electrical parameter equivalence before substitution. Note that packaging variations may exist between discontinued and current production runs.
