EVAL-AD7622CB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-AD7622CB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-AD7622CB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 AD7622 is a 16-bit, 2 MSPS, charge redistribution SAR, fully differential, analog-to-digital converter (ADC) that operates from a single 2.5 V power supply. The part contains a high speed, 16-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and both serial and parallel system interface ports. It features two very high sampling rate modes (wideband warp and warp) and a fast mode (normal) for asynchronous rate applications. The AD7622 is hardware factory calibrated and tested to ensure ac parameters, such as signal-to-noise ratio (SNR), in addition to the more traditional dc parameters of gain, offset, and linearity. The AD7622 is available in Pb-free only packages with operation specified from −40°C to +85°C.
