ADS8507IDW集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8507IDW属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8507IDW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。

DESCRIPTION

The ADS8507 is a complete low power, single 5-V

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 data interface. The converter can be

configured for a variety of input ranges including ±10

V, 4 V, and 5 V. For most input ranges, the input

voltage can swing to 25 V or –25 V without damage

to the converter.

A SPI compatible serial interface allows data to be

synchronized to an internal or external clock. A full

parallel interface with BYTE select is also provided to

allow the maximum system design flexibility. The

ADS8507 is specified at 40 kHz sampling rate over

the industrial -40°C to 85°C temperature range.
