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.
