ADI targets communications, instrumentation markets with 14bit a/d converters
1 min read
Analog Devices has announced the launch of two new single and dual channel 14bit a/d converters. Said to feature high speed and high accuracy, the devices are designed for use in communications, instrumentation and test and measurement applications.
The converters 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, handheld instruments, scopes and portable medical devices.
The AD9648 is a low power, 14bit a/d converter, which consumes 102mW/channel at 125Ms/s and features SFDR performance of 91dBc at 70MHz. With IF sampling frequencies up to 200MHz, ADI claims the device is a good choice for designers looking for a dual high speed a/d converter to build multimode digital receivers.
Housed in a 5 x 5mm package size, the AD9642 converter features IF sampling frequencies up to 350MHz, supports bandwidths up to 125MHz and is said to offer a 30% reduction in board space compared to competing products. It features an SNR of 72.2dBFS and SFDR of 90dBc at base band, while consuming 360mW at 250Ms/s.
The AD9648 and AD9642 both feature multi stage, differential pipelined architectures with integrated output error correction logic. The AD9648 is available in a 64lead RoHS compliant LFCSP, while the AD9642 ships in a 32lead RoHS compliant LFCSP package. Both are specified over the industrial temperature range of -40 to 85°C.
