ADS8481IB集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8481IB属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8481IB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 ADS8481 is an 18-bit, 1-MSPS A/D converter

with an internal 4.096-V reference and a

pseudo-differential unipolar single-ended input. The

device includes a 18-bit capacitor-based SAR A/D

converter with inherent sample and hold. The

ADS8481 offers a full 18-bit interface, a 16-bit option

where data is read using two read cycles, or an 8-bit

bus option using three read cycles.

The ADS8481 is available in a 7x7 QFN package

and is characterized over the industrial –40°C to

85°C temperature range.
