Texas Instruments has introduced what they say is the market's first 16-bit, single-channel, 200 megasample-per-second (MSPS) analog-to-digital converter (A/D) to provide faster speeds, previously only available with lower resolution A/Ds. The new data converters enable new levels of performance in communications, test and measurement, and defense applications.

The ADS5485 delivers speed, resolution and ultra-low noise to optimize performance in these applications. For instance, the A/D can achieve a signal-to-noise ratio of 75 dBFS (decibels Full Scale) and a spurious-free dynamic range of 87 dBc for a 70-MHz input frequency. The ADS5485 eases analog front end design by incorporating a fully differential input buffer. The buffer provides constant input impedance over the input frequency range and eliminates kickback from the A/D's track-and-hold structure to ensure consistent linearity of the signal.

The device enables 16-bit resolution with up to 100-MHz bandwidth for high-speed digitizers, spectrum analyzers, test and measurement equipment, and general data acquisition systems. It also enables sampling of larger bandwidths in radar systems, resulting in enhanced tracking resolution and object discrimination. Finally, it allows software-defined radios to implement a number of standards — such as WiMAX, LTE and CDMA.

The ADS5485 is priced at $98.95 1000-piece quantities. The device is available in a 9 x 9 mm, 64-pin QFN package.
