16-bit ADC from ADI offer sample rates of 250 MSPS

Analog Devices, Inc. (ADI) has released the AD9467, a 16-bit ADC at 250 MSPS (mega samples per second). ADI says that the ADC operates on 35% less power at 25% higher sampling rate than any other 16-bit data converter. This is suggested for signal processing for test and measurement instrumentation, defense electronics, and communications applications. The AD9467 can be used with ADI's AD9523/24 low-jitter clock generators and ADL5562 3.3 GHz ultra-low distortion RF/IF differential amplifier to provide a data conversion signal chain solution. The device offers a SFDR of 90 dBFS up to 300 MHz analog input and 60-femtosecond rms (root mean square) jitter.

"We needed a 16-bit, 250 MSPS data converter with 90 db of SFDR for one of our key customer's highly advanced, data acquisition systems," said Brian Kimball, principal hardware engineer, Mercury Computer Systems, a leading provider of open, application-ready, multi-INT subsystems for the intelligence, surveillance and reconnaissance market "The AD9467 data converter was designed into this system because it met our customer's SFDR, ENOB (effective number of bits), and power requirements. Analog Devices engineers worked with us as trusted advisors to provide early-access silicon and provided design support to enable the timely development of our prototype product."

"The AD9467 converter is attractive to National Instruments because of its industry-leading combination of sample rate and resolution," said Phil Hester, senior vice president of R&D, National Instruments, a leading global supplier of hardware and software for engineers. "We are currently developing a module based on the AD9467 for our NI FlexRIO product family, which couples this new data conversion performance point with FPGAs that can be programmed using NI LabVIEW software. The AD9467 helps us maintain leadership in providing innovative solutions for test and measurement, software-defined radio, medical imaging, and scientific research applications."

The AD9467 16-bit, 250 MSPS ADC includes on-chip IF (intermediate frequency) sampling circuit and buffered analog inputs. This ADC enables software-defined radios for use with multiple standards, such as LTE/W-CDMA, MC-GSM (class 1) and CDMA. Programmable full-scale input range allows trade-off between SNR and SFDR enabling the design of more sensitive radar systems with the ability to acquire and track smaller targets.
