The ADS801 is a low-power, monolithic 12-bit, 25MHz Analog-to-Digital (A/D) converter utilizing a small geometry CMOS process. This complete converter includes a 12-bit quantizer, wideband track-and-hold, reference, and three-state outputs. It operates from a single +5V power supply and can be configured to accept either single-ended or differential input signals. The ADS801 employs digital error correction to provide excellent Nyquist differential linearity performance for demanding imaging applications. Its low distortion, high SNR, and high-oversampling capability give it the extra margin needed for telecommunications, instrumentation, and video applications. This high-performance A/D converter is specified over temperature for ac and DC performance at a 25MHz sampling rate. The ADS820 is available in an SO-28 package.
