ADS828E/1K集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS828E/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ADS828E/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 ADS828 is a pipeline, CMOS analog-to-digital converter

that operates from a single +5V power supply. This

converter provides excellent performance with a singleended

input and can be operated with a differential input for

added spurious performance. This high performance converter

includes a 10-bit quantizer, high bandwidth track/

hold, and a high accuracy internal reference. It also allows

for the user to disable the internal reference and utilize

external references. This external reference option provides

excellent gain and offset matching when used in multichannel

applications or in applications where full scale

range adjustment is required.

The ADS828 employs digital error correction techniques to

provide excellent differential linearity for demanding imaging

applications. Its low distortion and high SNR give the

extra margin needed for medical imaging, communications,

video, and test instrumentation. The ADS828 offers power

dissipation of 325mW and also provides a power-down

mode, thus reducing power dissipation to only 20mW.

The ADS828 is specified at a maximum sampling frequency

of 75MHz and a single-ended input range of 1.5V to 3.5V.

The ADS828 is available in a SSOP-28 package and is pin

compatible with the 10-bit, 40MHz ADS822 and ADS825,

and the 10-bit, 60MHz ADS823 and ADS826.
