The ADS58B18 is an 11-bit analog-to-digital converter (ADCs) with sampling rates up to 200MSPS and integrated analog input buffers. This device uses innovative design techniques to achieve high dynamic performance, while consuming extremely low power.The analog input pins have buffers, with benefits of constant performance and input impedance across a wide frequency range. The ADS58B18 is well-suited for multi-carrier, wide bandwidth communications applications.
The ADS58B18 is an 11-bit analog-to-digital converter (ADC) featuring a maximum sample rate of 200 MSPS and integrated high-impedance analog input buffers. It utilizes TI's proprietary SNRBoost technology to enhance signal-to-noise ratio in bandwidths less than the Nyquist frequency, making it suitable for multi-carrier, wide-bandwidth communications applications.
The device supports both Double Data Rate (DDR) LVDS and parallel CMOS digital output interfaces. Key features include programmable gain up to 6dB, DC offset correction, and dynamic power scaling based on the sample rate. The ADS58B18 is available in a compact QFN-48 package specified for industrial temperature ranges.
