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.
The device uses an integrated adaptive bias current control circuit to minimise crossover distortion even while consuming 54% lower quiescent supply current than other competitive devices.
Additionally, the FAN7021's exceptionally low bias-supply current, combined with low-shutdown current consumption (0.15A), saves energy and extends battery life.
With typical total harmonic distortion (THD) of 0.2% and exceptional power supply rejection ratio (PSRR) of 65dB, the FAN7021 delivers high-quality output performance in portable audio applications.
The FAN7021 power amplifier also features a built-in popping noise reduction circuit to reduce unexpected speaker noise when the system's power is turned on or off.
The FAN7021 reduces overall system footprint by not requiring an output coupling capacitor, a bootstrap capacitor, or a snubber network.
Other features include thermal shutdown protection, unity gain stability, and external gain configuration capability.
The FAN7021 is offered in an 8-SOP package and comes in tube or tape-and-reel packing, with 1000-off pricing starting at US $0.55.
