14-bit analog to digital convertersAnalog Devices released single and dual-channel 14-bit high-speed A/D converters for use in communications, instrumentation and test and measurement applications. The new converters are asserted to meet the performance and small size requirements of the latest 3G and 4G multi-standard cellular infrastructure equipment such as CDMA2000, WB-CDMA, LTE, TD-SCDMA and multi-carrier GSM. Other applications include battery-powered, hand-held instruments, scopes and portable medical devices. The AD9648 is a low-power, high-speed, 14-bit dual A/D converter that consumes 102 mW/channel at 125 MSPS and features SFDR performance of 91 dBc at 70 MHz. With IF sampling frequencies up to 200 MHz, the ADC is desirable for designers looking for a dual high-speed A/D converter to build multimode digital receivers. Analog Devices’ AD9642 14-bit A/D single-channel converter features a 5 mm x 5 mm package size and IF sampling frequencies up to 350 MHz. It supports wide bandwidths up to 125 MHz and features an SNR (signal-to-noise ratio) of 72.2 dBFS and SFDR of 90 dBc at base band while consuming 360 mW at 250 MSPS.
