ADS8515IDBR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8515IDBR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8515IDBR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 ADS8515 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, SAR A/D converter with sample and

hold (S/H), reference, clock, interface for

microprocessor use, and 3-state output drivers.

The ADS8515 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 ADS8515 is available in a 28-pin SSOP package

and is fully specified for operation over the industrial

–40°C to 85°C temperature range.
