Product introduction

peculiarity

I 2 C-compatible 2-wire interface supporting standard (100kHz), fast (400kHz) and high-speed modes (3.4MHz)
扩展的电源电压范围（2.7 V至+5.5 V）
Up to 9 pin-selectable chip addresses (MSOP - 8 only)
Scoped alert capabilities
Automatic power-down mode, not conversion
Very small TSOT-6 and MSOP-8 packages
± 8 kV HBM ESD protection (SDA, SCL)

这些转换器是低功耗，单片集成电路，12位，模拟到数字转换器（ADC），从2.7至5.5V电源运作。该转换器是基于逐次逼近寄存器结构与内部跟踪和保持电路，可处理高达11MHz的输入频率。这些转换器工作从单一的供应，这也作为参考。 The device has I 2 C compatible Serial interface that operates in all three speed modes, including high-speed mode (3.4MHz).

ADC121C021的警报功能，提供了一个模拟输入违反了可编程的上限或下限值被激活时，中断。 The device features an automatic conversion mode that releases the controller and I 2 C interface. 在这种模式下，ADC的连续监测“范围的”条件的模拟输入，并提供了一个中断，如果测得的电压超出范围的。

ADC121C021来在两个包：一个小TSOT - 6封装与警报输出，采用MSOP - 8与警报输出和2个地址选择输入包。 “ ADC121C027 In a small TSOT-6 package, with an address selection input. “ ADC121C027 提供三个引脚可选择的地址，而采用MSOP - 8版本的ADC121C021提供了9个引脚可选择的地址。引脚兼容的替代品TSOT - 6选项提供额外的地址选项。

，正常使用+3 V或+5 V电源的功耗0.26mW 0.78mW，分别。 Automatic power-down function reduces power consumption by less than 1μW without conversion. 运行在工业温度范围为-40 ° C至+105 ° C的保证。其低功耗和小封装使此系列ADC在使用电池供电设备的极佳选择。

“ ADC121C021 and ADC121C027 一个引脚兼容的8和10位分辨率的ADC，还提供家庭的一部分。对于8位ADC看到 ADC081C021 and ADC081C027 。 For 10-bit ADCs see ADC101C021 and ADC101C027 。
