EVAL-AD7264EDZ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-AD7264EDZ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-AD7264EDZ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 AD7264 is a dual, 14-bit, high speed, low power, successive approximation ADC that operates from a single 5 V power supply and features throughput rates of up to 1 MSPS per on-chip ADC (500 kSPS for the AD7264-5). Two complete ADC functions allow simultaneous sampling and conversion of two channels. Each ADC is preceded by a true differential analog input with a PGA. There are 14 gain settings available: ×1, ×2, ×3, ×4, ×6, ×8, ×12, ×16, ×24, ×32, ×48, ×64, ×96, and ×128.
