AD7441集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

AD7441属于集成电路（IC）的ADC/DAC-特殊用途。由亚德诺半导体技术有限公司制造生产的AD7441ADC/DAC - 特殊用途该产品族中的产品可用于模拟和数字表示的信息转换，适用于特定用例，或集成了通用数据转换器中不常见的其他功能。例如针对超声或汽车雷达应用集成了低噪声放大器和可变增益级的器件、注重音频和视频的产品、在段码式显示器上集成显示测量值功能的器件、集成输入输出电气隔离的器件等。

GENERAL DESCRIPTION

The AD7441/AD74511 are, respectively, 10-/12-bit high speed, low power, single-supply, successive approximation (SAR), analog-to-digital converters (ADCs) that feature a pseudo differential analog input. These parts operate from a single 2.7 V to 5.25 V power supply and achieve very low power dissipation at high throughput rates of up to 1 MSPS.

The AD7441/AD7451 contain a low noise, wide bandwidth, differential track-and-hold (T/H) amplifier that handles input frequencies up to 3.5 MHz. The reference voltage for these devices is applied externally to the VREF pin and can range from 100 mV to VDD, depending on the power supply and what suits the application.
