ADS8513中文资料具有内部基准和并行/串行接口的 16 位 40kSPS 低功耗采样 ADC数据手册TI规格书

描述 Description

The ADS8513 is a complete low-power, single 5V supply, 16-bit sampling analog-to-digital (A/D) converter. It contains a complete 16-bit capacitor-based, successive approximation register (SAR) A/D converter with sample and hold, clock, reference, and serial data interface. The converter can be configured for a variety of input ranges including ±10 V, ±5V, 0V to 10V, and 0.5V to 4.5V. A high-impedance, 0.3V to 2.8V input is also available with input impedance greater than 10MΩ. For most input ranges, the input voltage can swing to 25V or -25V without damage to the converter.
AnSPI-compatible serial interface allows data to be synchronized to an internal or external clock. The ADS8513 is specified at 40kSPS sampling rate over the industrial -40°C to +85°C temperature range.

简介

ADS8513属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADS8513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。
