Tiny packaging for hifi analogue switches
Three new analogue switches for cellphone audio circuits feature low total harmonic distortion and flat on-resistance characteristics to provide the best possible audio fidelity.
Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
Replacing two (in series) single-pole/double-throw (SPDT) components with a single 3:1 mux FSA3357 device lowers part count by 50%, provides superior utilisation of PCB real estate, preserves signal integrity and reduces equivalent component pick-and-place operations by half.
Available in US8 packaging, the FSA3357 SP3T analogue switch provides smaller size and better performance than the dual 2:1 mux devices required for equivalent functionality.
The high-performance FSA3357 SP3T analogue switch features an on-resistance of only 6ohm, resulting in minimal signal attenuation.
The device's 0.01% total harmonic distortion (THD), coupled with its -60dB crosstalk characteristic, ensures signal integrity.
Its wide bandwidth (250MHz) and rail-to-rail signal handling guarantee extremely fast, clip-free transfer of analogue and digital signals.
A wide supply range of 1.65 to 5.5V makes the FSA3357 device ideal for battery applications.
The FSA3357 SP3T device is the latest addition to Fairchild's analogue switch family featuring ultra-small package devices in SC70, SOT23, leadless MicroPak and US8 form factors.
Fairchild reckons it offers the industry's best combination of device functionality, packaging options and pricing.
