说明

ADS1113-Q1、ADS1114-Q1 和 ADS1115-Q1 器件 (ADS111x-Q1) 是采用 VSSOP-10 和 UQFN-10 封装、兼容 I2C 的 16 位低功耗精密模数转换器 (ADC)。ADS111x-Q1 器件采用了低漂移电压基准和振荡器。ADS1114-Q1 和 ADS1115-Q1 还包含一个可编程增益放大器 (PGA) 和一个数字比较器。除了这些特性,ADS111x-Q1 还具有宽工作电源电压范围,因此非常适合功率受限型和空间受限型传感器测量应用。

ADS111x-Q1 可在数据速率高达每秒 860 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。ADS1115-Q1 具有一个输入多路复用器 (MUX),可实现双路差分输入或四路单端输入测量。在 ADS1114-Q1 和 ADS1115-Q1 中使用数字比较器可进行欠压和过压检测。
