ADC101S021中文资料配备 SPI 的 10 位、200kSPS、单通道 SAR ADC数据手册TI规格书

描述 Description

The ADC101S021 is a low-power, single channel CMOS 10-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC101S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The converter is based upon a successive-approximation register architecture with an internal track-and-hold circuit.The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many common DSP serial interfaces.The ADC101S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3.6V or +5.25V supply is 2.34 mW and 8.9 mW, respectively. The power-down feature reduces the power consumption to as low as 2.6 µW using a +5.25V supply.The ADC101S021 is packaged in 6-lead WSON and SOT-23 packages. Operation over the industrial temperature range of −40°C to +85°C is ensured.

简介

ADC101S021属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADC101S021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。
