Dallas, Tex.Texas Instruments Inc. (TI) has introduced the market's first 16-bit, single-channel, 200 mega samples per second (MSPS) A/D converter to provide faster speeds previously only available with lower resolution devices.
The ADS5485 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 A/D converter's track-and-hold structure to ensure consistent linearity of the signal.
The performance of the ADS5485 increases design flexibility and offers a number of system-level benefits in communications, test and measurement and defense applications. It 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 improves transmit power amplifier linearization and efficiency combined with a digital pre-distortion algorithm, lowering total system cost.
The ADS5485 enables sampling of larger bandwidths in radar systems, resulting in enhanced tracking resolution and object discrimination. It also allows software-defined radios to implement a greater number of standards such as WiMAX, LTE and CDMA.
The ADS5485 expands TI's ADS548x family of high-speed, ultra-low-noise A/D converters. The devices are available in a space-saving 9 x 9 mm, 64-pin QFN package.
