FEATURES  
DESCRIPTION  
250kHz SAMPLING RATE  
COMPLETE WITH S/H, REF, CLOCK, ETC.  
96dB min SFDR WITH 100kHz INPUT  
84dB min SINAD  
The ADS7815 is a complete 16-bit sampling analog-  
to-digital (A/D) converter featuring excellent AC  
performance and a 250kHz throughput rate. The de-  
sign 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.
