Analog Devices Inc. (ADI) released new single and dual-channel 14-bit high-speed A/D converters for use in communications, instrumentation and test and measurement applications.
The AD9648 is a low-power, high-speed, 14-bit dual A/D converter that consumes 102 mW/channel at 125 MSPS (mega samples per second) and features SFDR (spurious-free dynamic range) performance of 91 dBc at 70 MHz. With IF sampling frequencies up to 200 MHz, the AD9648 is a good choice for designers looking for a dual high-speed A/D converter to build multimode digital receivers.
ADI also released the AD9642 14-bit A/D single-channel converter. With a 5 mm x 5 mm package size — 30 percent smaller than competing products — and IF sampling frequencies up to 350 MHz, the AD9642 saves board space and supports wide bandwidths up to 125MHz, according to the company. It 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.
AD9648 key features:
SNR = 74.5 dBFS at fIN up to 70 MHz at 125 MSPS
ENOB of 11.8 at fIN up to 70 MHz at 125 MSPS (-1.0 dBFS)
SFDR = -91 dBc at fIN up to 70 MHz at 125 MSPS (-1.0 dBFS)
