ADS800中文资料12 位、40MSPS ADC 单端/差分输入内部基准电压，引脚与 ADS801/2 兼容数据手册TI规格书

描述 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/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.

简介

ADS800属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADS800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。
