ADS7807屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由美國(guó)德州儀器公司制造生產(chǎn)的ADS7807模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)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(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)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(jìn)行選擇。

DESCRIPTION

The ADS7807 is a low-power, 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, clock, reference, and microprocessor interface

with parallel and serial output drivers.

The ADS7807 can acquire and convert 16 bits to within

±1.5LSB in 25μs max while consuming only 35mW max.

Laser trimmed scaling resistors provide standard industrial

input ranges of ±10V and 0V to +5V. In addition, a 0V to +4V

range allows development of complete single-supply systems.

The ADS7807 is available in a 0.3 DIP-28 and SO-28, both

fully specified for operation over the industrial –40°C to

+85°C temperature range.
