ADS7811数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 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.
