Texas Instruments Inc. (TI) has just announced a new 14-bit, 125-MSPS (mega samples per second) analog-to-digital converter (ADC). The very high sampling rate allows increased system capabilities in advanced communications, test and measurement, medical, and imaging applications, while the low total power dissipation (750 mW) improves system reliability and allows higher channel density. The ADS5500, operating at 125 MSPS, features 70-dB SNR and 82-dB SFDR at 100-MHz input frequency. The performance of the ADS5500 enables a wide range of benefits such as improved receiver performance in wireless communications, higher quality imaging in video systems, extended signal analysis capabilities for test equipment, and more precise scans and lower magnetic field energy in medical Magnetic Resonance Imaging (MRI) equipment. The low power dissipation reduces power supply requirements and the need for thermal management (cooling), resulting in smaller footprint and equipment size, and higher circuit density. The power savings also enables next-generation, high-performance portable wireless, test and measurement and video Imaging systems.
