Fairchild Semiconductor offers 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 MicroPak packaging, all products offer greater than 65% space savings over traditional SC70 and SOT-23 packages.
Key features: RON is maximum of 1,0 to 1,35 Ω; broad operating voltage range - 1,65 to 5,5 V; low THD - 0,002% typical; RON flatness - 0,2 Ω typical.
Incorporating features that are important to a wide range of customers and applications: the wide operating range provides the added benefit of protecting cellphone batteries from damage caused by overcharges; higher operating voltage enables them to easily accommodate overcharges of up to 4,6 V, which typical 3,3 V-rated analog switches cannot do; the greater than 350 MHz 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 7500 V (HBM).
