Texas Instruments Launches 16-bit Analog-to-Digital Converter

Texas Instruments Incorporated has introduced its 16-bit, single-channel, 200 mega samples per second (MSPS) analog-to-digital converter (ADC) to provide faster speeds previously only available with lower resolution ADCs. The new data converters enable new levels of performance in communications, test and measurement, and defense applications. Evaluation modules (EVMs) simplify design and enable rapid evaluations of these complex systems. The ADS5485 delivers speed, resolution and ultra-low noise to optimize performance in these applications. For instance, the ADC can achieve a signal-to-noise ratio of 75 dBFS and a spurious-free dynamic range of 87 dBc for a 70-MHz input frequency (IF). The ADS5485 eases analog front end design by incorporating a fully differential input buffer. Developed in TI’s BiCom3 high-speed process technology, this buffer provides constant input impedance over input frequency and eliminates kickback from the ADC’s track-and-hold structure to ensure consistent linearity of the signal.



The ADS5485 expands TI’s ADS548x family of high-speed, ultra-low-noise ADCs. The devices are available in a space-saving 9 x 9 mm, 64-pin QFN package and suggested resale pricing for each is listed below in 1000-piece quantities. The samples of all five members of the ADS548x family are available today. In addition, TI offers a number of tools to simplify design. For instance, the ADS5485 and the CDCE72010 low-jitter clock are available on the same evaluation module (EVM) to facilitate fast evaluations of complex systems.
