® ADS 820 U ADS820 ADS 820 E 10-Bit, 20MHz Sampling ANALOG-TO-DIGITAL CONVERTER TM FEATURES q NO MISSING CODES q INTERNAL REFERENCE q LOW DIFFERENTIAL LINEARITY ERROR: 0.2LSB q LOW POWER: 195mW q HIGH SNR: 60dB q WIDEBAND TRACK/HOLD: 65MHz q PACKAGES: 28-Pin SOIC and 28-PIN SSOP DESCRIPTION The ADS820 is a low power, monolithic 10-bit, 20MHz analog-to-digital converter utilizing a small geometry CMOS process. This COMPLETE converter includes a 10-bit quantizer with internal track/hold, reference, and a power down feature. It operates from a single +5V power supply and can be configured to accept either differential or single-ended input signals. The ADS820 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 and video applications. This high performance converter is specified for AC and DC performance at a 20MHz sampling rate. The ADS820 is available in 28-pin SOIC and SSOP packages.
