ADS8515IDBR屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由美國德州儀器公司制造生產(chǎn)的ADS8515IDBR模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對模擬信號進行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號。一般來說，數(shù)字輸出是二進制補碼二進制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。

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.
