EVAL-AD7176-2SDZ开发板套件编程器的评估板-模数转换器（ADC）规格书PDF中文资料

EVAL-AD7176-2SDZ属于开发板套件编程器的评估板-模数转换器（ADC）。由亚德诺半导体技术有限公司制造生产的EVAL-AD7176-2SDZ评估板 - 模数转换器（ADC）模数转换器 (ADC) 评估板是预装有元器件的电路板，用于提供特定 ADC 或器件工作实例。特定板上的 A/D 转换器数量从 3 到 32 不等，每秒采样率从 2.5 kHz 到 26 GHz 不等，输入电压范围从 0 到 8 Vp-p。

GENERAL DESCRIPTION

The AD7176-2 is a fast settling, highly accurate, high resolution, multiplexed Σ-Δ analog-to-digital converter (ADC) for low bandwidth input signals. Its inputs can be configured as two fully differential or four pseudo differential inputs via the integrated crosspoint multiplexer. An integrated precision, 2.5 V, low drift (2 ppm/°C), band gap internal reference (with an output reference buffer) adds functionality and reduces the external component count.
