ADS800U/1K集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS800U/1K属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS800U/1K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 ADS800 is a low-power, monolithic 12-bit, 40MHz Analog-

to-Digital (A/D) converter utilizing a small geometry CMOS

process. This complete converter includes a 12-bit quantizer,

wideband track-and-hold, reference, and three-state outputs.

It operates from a single +5V power supply and can be

configured to accept either differential or single-ended input

signals.

The ADS800 employs digital error correction to provide

excellent Nyquist differential linearity performance for demanding

imaging applications. Its low distortion, high SNR,

and high oversampling capability give it the extra margin

needed for telecommunications, test instrumentation, and

video applications.

This high-performance A/D converter is specified over temperature

for AC and DC performance at a 40MHz sampling

rate. The ADS800 is available in an SO-28 package.
