q 96dB min SFDR WITH 100kHz INPUT q 84dB min SINAD q ±2.
5V INPUT RANGE q 28-LEAD SOIC APPLICATIONS q WIRELESS BASE STATIONS q SPECTRUM ANALYSIS q IMAGING SYSTEMS q DATA ACQUISITION DESCRIPTION The ADS7811 is a complete 16-bit sampling analog-todigital (A/D) converter featuring excellent AC performance and a 250kHz throughput rate.
The design includes a 16-bit capacitor-based SAR A/D converter with an inherent sample and hold (S/H), a precision reference, and an internal clock.
Spurious-free dynamic range with a 100kHz full-scale sinewave input is typically greater than 100dB.
The ±2.
5V input range allows development of precision systems using only ±5V supplies.
The converter is available in a 28-lead SOIC package specified for operation over the industrial –25°C to +85°C temperature range.
