DESCRIPTION

The ADS7815 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.
