EVAL-AD7450ACB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-AD7450ACB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-AD7450ACB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 AD7440/AD7450A1 are 10-bit and 12-bit high speed, low power, successive approximation (SAR) analog-to-digital converters with a fully differential analog input. These parts operate from a single 3 V or 5 V power supply and use advanced design techniques to achieve very low power dissipation at throughput rates up to 1 MSPS. The SAR architecture of these parts ensures that there are no pipeline delays.

The parts contain a low noise, wide bandwidth, differential track-and-hold amplifier (T/H) that can handle input frequencies up to 3.5 MHz. The reference voltage is applied externally to the VREF pin and can be varied from 100 mV to 3.5 V depending on the power supply and what suits the application. The value of the reference voltage determines the common-mode voltage range of the part. With this truly differential input structure and variable reference input, the user can select a variety of input ranges and bias points.
