TI's Expanded Fully-Differential Amplifier Portfolio Drives Easy Interface to High-Speed Analog-to-Digital Converters

via PRNewswire

DALLAS, Oct. 26 /PRNewswire/ -- Texas Instruments Incorporated (NYSE: TXN)(TI) introduced today three additions to its high-performance family of low-noise, low-distortion, fully differential amplifiers that drive high-speed analog-to-digital converters (ADC) in demanding applications such as test and measurement, medical imaging, wireless infrastructure and industrial applications. Providing more flexibility to meet the needs of high-speed data acquisitions systems, the family allows designers to choose between high gain and unity gain stable, and between negative and mid-supply input common-mode voltages, the company says.

Designed for 3.3 to 5-volt data acquisition systems, the THS4511 and THS4513 unity gain stable versions, and the THS4508 amplifier are based on the previously announced THS4509. The three devices feature fully differential architecture and 5-V single supply operation. Depending on the device, bandwidths for the devices range from 1600 to 2000 megahertz with slew rates from 4900 to 6400 volts per microsecond. The amplifiers are also characterized for operation over the full industrial temperature range from -40 to +85 degrees Celsius.

When used along with a high-speed ADC like the ADS5424, 14-bit, 105-MSPS, ADC, The THS4508/9/11/13's DC precision, and noise and distortion performance enable the designer to ensure accurate low-level signal measurements and high signal fidelity, while simplifying the design process and reducing the overall solution size. In addition, these amplifiers and data converters interface with the TMS320C6000 DSP products in a high-performance signal chain for wideband applications.
