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)
- Integrated input buffer
- Excellent linearity
- DNL = ±0.5 LSB typical
- INL = ±1.0 LSB typical
- 12-bit and 10-bit pin compatible devices include AD9628 and AD9608 high-speed A/D converters
AD9642 key features :
- SNR = 70.9 dBFS at 200 MHz AIN and 250 MSPS
- SFDR = 86 dBc at 200 MHz AIN and 250 MSPS
- -152.0 dBFS/Hz input noise @ 200 MHz, -1dBFS AIN and 250 MSPS
- Total power consumption: 360 mW @ 250 MSPS
- 12-bit and 11-bit pin compatible devices include AD9634 high-speed A/D converter and the AD6672 IF receiver
