ADS7811U集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7811U属于集成电路（IC）的模数转换器（ADC）。由美国德州仪器公司制造生产的ADS7811U模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

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.
