The ADS7815 is a complete 16bit sampling analogtodigital (A/D) converter featuring excellent AC performance and a 250kHz throughput rate. The design includes a 16bit capacitorbased SAR A/D converter with an inherent sample and hold (S/H), a precision reference, and an internal clock. Spuriousfree dynamic range with a 100kHz fullscale 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 28lead SOIC package specified for operation over the industrial 25°C to +85°C temperature range.
