TI unveils fastest 16bit ADC

Keywords:200MSPS  ADC  differential input buffer  16bit resolution 

Texas Instruments Inc. (TI) has introduced what it claims as the market's first 16bit, single-channel, 200MSPS ADC to provide faster speeds previously only available with lower resolution devices.

The ADS5485 can achieve a signal-to-noise ratio of 75dBFS and a spurious-free dynamic range of 87dBc for a 70MHz input frequency (IF). The ADS5485 eases analogue 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 performance of the ADS5485 offers a number of system-level benefits in communications, test and measurement and defence applications. It enables 16bit resolution with up to 100MHz bandwidth for high-speed digitisers, spectrum analysers, test and measurement equipment, and general data acquisition systems. It also improves transmit power amplifier linearisation and efficiency combined with a digital predistortion 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 ADCs. The devices are available in a space-saving 9mm x 9mm, 64-pin QFN package.
