AD9255BCPZ-105

AD9255 is a 14-bit, 105MSPS analogue to digital converter (ADC). The AD9255 is designed to support communications applications where high performance combined with low cost, small size and versatility is desired. The ADC features a wide bandwidth differential sample-and hold analogue input amplifier supporting a variety of user-selectable input ranges. It is suitable for multiplexed systems that switch fullscale voltage levels in successive channels and for sampling single channel inputs at frequencies well beyond the Nyquist rate. Combined with power and cost savings over previously available ADCs, the AD9255 is suitable for applications in communications, instrumentation and medical imaging. It is suitable for use in communications multimode digital receivers (3G), GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX and TD-SCDMA, smart antenna systems, general-purpose software radios, broadband data applications and ultrasound equipment.
