ADS830E/2K5集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS830E/2K5属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS830E/2K5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 ADS830 is a pipeline, CMOS Analog-to-Digital (A/D)

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 an 8-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

multi-channel applications or in applications where DC full

scale range adjustment is required.

The ADS830 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 ADS830 is specified at a maximum sampling frequency

of 60MHz and a single-ended input range of 1.5V

to 3.5V. The ADS830 is available in a SSOP-20 package

and is pin-for-pin compatible with the 8-bit, 80MHz ADS831.
