ADI's new 14-bit high-speed ADC challenges higher performance requirements

ADI global leader in high-performance signal processing solutions provider, recently introduced a new single-channel and dual-channel 14-bit, high-speed analog to digital converter AD9642 and AD9648 . These compact, cost-effective, and flexible devices feature high speed and high accuracy for communication, instrumentation, test and measurement applications. New converter Capable of meeting the high performance and small size requirements of the latest 3G and 4G multi-standard cellular communication infrastructures such as CDMA2000, WB-CDMA, LTE, TD-SCDMA, multi-carrier GSM, etc. Other applications include battery-powered handheld instruments, oscilloscopes, and portable medical devices.

The AD9648 is a low power, high speed, 14-bit dual ADC that operates at a sampling rate of 125 MSPS (million samples per second) with a power consumption of 102 mW per channel; at 70 MHz input, SFDR ( The spurious-free dynamic range performance is 91 dBc. With an IF sampling frequency of up to 200 MHz, the AD9648 is a good choice for designers looking to build a multimode digital receiver with a dual high-speed ADC. The AD9648 is pin compatible with many of Analog Devices ' 16, 16, 12, and 10-bit ADCs, and 10-bit to 16-bit converters from 20 MSPS to 125 MSPS . It can be easily transplanted between.

In addition, Analog Devices recently introduced the AD9642 , a 14-bit single-channel ADC with a package size of 5 mm x 5 mm, which is 30% smaller than competing products. The IF sampling frequency is up to 350 MHz, so the AD9642 not only saves board space, but also saves board space. Supports wide bandwidth up to 125MHz. At baseband, the SNR (signal-to-noise ratio) is 72.2 dBFS with an SFDR of 90 dBc; when operating at 250 MSPS, the power consumption is only 360 mW.
