ADS8505IDWR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8505IDWR属于集成电路（IC）的模数转换器（ADC）。由美国德州仪器公司制造生产的ADS8505IDWR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 ADS8505 is a complete 16-bit sampling A/D

converter using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, SAR

A/D with S/H, reference, clock, interface for

microprocessor use, and 3-state output drivers.

The ADS8505 is specified at a 250-kHz sampling

rate over the full temperature range. Precision

resistors provide an industry standard ±10-V input

range, while the innovative design allows operation

from a single +5-V supply, with power dissipation

under 100 mW.

The ADS8505 is available in 28-pin SOIC and 28-pin

SSOP packages, both fully specified for operation

over the industrial –40°C to 85°C temperature range.
