The FSA4157L6XNL is a low on-resistance, single-pole/double-throw (SPDT) analog switch from Fairchild/ON Semiconductor. This switch is designed for use in portable devices and other applications requiring low power consumption, low distortion, and high bandwidth.

Applications:

• Cell Phones
• Tablets
• MP3 Players
• GPS Devices
• Audio and Data Signal Switching

Features:

• Low On-Resistance: 0.8Ω (typical) at 3.0V
• Wide Bandwidth: 300 MHz (typical)
• Low Power Consumption: ICC = 1μA (max)
• Single Supply Operation: 1.65V to 5.5V
• Break-Before-Make Switching
• Available in a small 6-lead X2DFN package

Benefits:

• Extends battery life in portable devices
• Preserves signal integrity in high-speed applications
• Saves board space
• Simplified design
• Prevents signal shorting during switching

Additional Details:

The FSA4157L6XNL is ideal for switching audio signals due to its low THD+N performance. The switch is controlled by a single digital input. Its small package size makes it suitable for densely populated circuit boards. The operating temperature range is -40°C to +85°C. This device is RoHS compliant.
