Texas Instruments Inc. announces three additions to its family of low noise, low distortion fully-differential amplifiers that drive high-speed analog-to-digital converters (ADC) in demanding 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. Designed for 3.3 to 5 V data acquisition systems, the THS4511 and THS4513 unity gain stable versions, and the THS4508 amplifier feature fully differential architecture and 5 V single supply operation. Depending on the device, bandwidths for the devices range from 1600 to 2000 MHz with slew rates from 4900 to 6400 V/µs. The THS4508/9/11/13 combine DC precision with good noise and distortion performance. When used along with a high-speed ADC like the ADS5424, 14-bit, 105-MSPS, ADC, these features enable the designer to ensure accurate low-level signal measurements and high signal fidelity, while greatly simplifying the design process and reducing the overall solution size.
