说明

ADS1013、ADS1014 和 ADS1015 器件 (ADS101x) 是兼容 I2C 的 12 位高精度低功耗模数转换器 (ADC),采用超小型无引线 X2QFN-10 封装和 VSSOP-10 封装。ADS101x 器件采用了低漂移电压基准和振荡器。ADS1014 和 ADS1015 还采用可编程增益放大器 (PGA) 和数字比较器。这些 特性以及较宽的工作电源电压范围使得 ADS101x 非常合适功率受限和空间受限的传感器测量 应用。

ADS101x 可在数据速率高达每秒 3300 个样本 (SPS) 的情况下执行转换。PGA 可提供从 ±256mV 到 ±6.144V 的输入范围,从而实现精准的大小信号测量。ADS1015 采用 一个输入多路复用器 (MUX),可实现两次差动输入测量或四次单端输入测量。在 ADS1014 和 ADS1015 中可使用数字比较器进行欠压和过压检测。

ADS101x 既可工作于连续转换模式下,也可工作于单冲模式下。在单冲模式下,这些器件可在一次转换后自动断电;因此显著降低了空闲期间的功耗。
