ADS8519IDBR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8519IDBR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ADS8519IDBR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 ADS8519 is a complete 16-bit sampling

analog-to-digital (A/D) converter using state-of-the-art

CMOS structures. It contains a complete 16-bit,

capacitor-based, successive approximation register

(SAR) A/D converter with sample-and-hold,

reference, clock, and a serial data interface. Data can

be output using the internal clock or synchronized to

an external data clock. The ADS8519 also provides

an output synchronization pulse for ease-of-use with

standard DSP processors.

The ADS8519 is specified at a 250kSPS sampling

rate over the full temperature range. Internal precision

resistors provide various input ranges including ±10V,

±5V, and 0V to 8.192V, while the innovative design

allows operation from a single 5V supply with power dissipation under 125mW.

The ADS8519 is available in a 28-pin SSOP

package, and is fully specified for operation over the industrial –40°C to +85°C temperature range.
