Analog Devices introduces a 14-bit, 80 MS/S ADC that offers high spurious-free dynamic range (SFDR). The first in a family of high-speed, high-resolution ADCs optimized to improve the robustness and simplify the design of advanced 3G and next-generation 4G wireless base stations, the AD9444 provides a typical SNR of 73.1 dB and SFDR of 97 dBc with a 70 MHz input. Optimized for wireless base station applications, its high SFDR also makes the AD9444 suited for test equipment, wireless broadband, and high-end data acquisition systems. The AD9444 provides high accuracy, with typical differential nonlinearity (DNL) of ± 0.4 LSB, integral nonlinearity (INL) of ± 0.6 LSB, and power dissipation of 1.2 W. The ADC also features parallel low-voltage differential signaling (LVDS) outputs, including an output clock, simplifying the interface to digital down-converters and reducing the potential for digital noise coupling back into the ADC core.
