ADS831E/2K5集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS831E/2K5属于集成电路（IC）的模数转换器（ADC）。由美国德州仪器公司制造生产的ADS831E/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 ADS831 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 single-ended 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 ADS831 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 ADS831 is specified at a maximum sampling frequency of

80MHz and a single-ended input range of 1.5V to 3.5V. The

ADS831 is available in an SSOP-20 package and is pin-for-pin

compatible with the 8-bit, 60MHz ADS830.
