в—Џ 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 В±2.5V input range allows development of precision systems using only В±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. 250kHz SAMPLING RATE
COMPLETE WITH S/H, REF, CLOCK, ETC.
