Designed with less than 0.002% Total Harmonic Distortion (THD) for audio fidelity
Fairchild Semiconductor announces three new low-Ohmic analog switch products—the FSA4157 Single Pole/Double Throw (SPDT), FSA1156 Normally Open Single Pole/Single Throw (SPST NO) and the FSA1157 Normally Closed Single Pole/Single Throw (SPST NC) switches. The devices' low ON Resistance (RON) preserves signal integrity and lowers the drive necessary to support audio and signal processing applications. Available in chip-scale MicroPakTM packaging, all products offer greater than 65% space savings over traditional SC70 and SOT-23 packages, as well as:
• Low ON Resistance (RON)—maximum of 1.0 to 1.35 Ohms
• Broad operating voltage range—1.65 to 5.5V
• Low THD—0.002% typical
• Low RON Flatness—0.2 Ohm typical
By design, Fairchild's analog switches incorporate features that are important to a wide range of customers and applications. These universal switches make selection simpler, reduce qualification and inventory costs, and provide superior performance for easy re-use in system upgrades. The wide 1.65-5.5V operating range of these devices provides the added benefit of protecting cell phone batteries from damage caused by overcharges. The higher operating voltage of the Fairchild switches enables them to easily accommodate overcharges of up to 4.6V, which typical 3.3V-rated analog switches cannot do. The greater than 350MHz bandwidth of the Fairchild devices supports high-speed analog and digital signal routing in low-voltage applications, while providing industry-leading ESD protection of better than 7500V (HBM).
The low-Ohmic analog switches add to Fairchild's portfolio of products targeting portable applications. These products include audio amplifiers, LED drivers and LEDs for backlighting, supervisory products such as temperature sensors and reset generator circuits, and DC/DC conversion products such as DC/DC converters, LDOs and MOSFETs.
