描述 Description

The ADS801 is a low-power, monolithic 12-bit, 25MHz 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 single-ended or differential input signals. The ADS801 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, instrumentation, and video applications. This high-performance A/D converter is specified over temperature for ac and DC performance at a 25MHz sampling rate. The ADS820 is available in an SO-28 package.

简介

ADS801属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADS801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。
