AD9762ARU全新原装由AD原厂生产,采用TSSOP-28封装,批号12+,微芯百年集成电路仓库目前有库存
12-bit, 100 MSPS+ TxDAC digital-to-analog® converter
AD9762属于TxDAC系列高性能、低功耗CMOS数模转换器(DAC)的12位分辨率产品。TxDAC系列由引脚兼容的8、10、12、14位DAC组成，并专门针对通信系统的发射信号路径进行了优化。所有器件都采用相同的接口选项、小型封装和引脚排列，因而可以根据性能、分辨率和成本，向上或向下选择适合的器件。AD9762提供出色的交流和直流性能，同时支持最高125 MSPS的更新速率。
The flexible single-supply operating voltage range (2.7 V to 5.5 V) and low power consumption of the AD9762 make it ideal for portable and low power applications. By reducing the full-scale current output, the power consumption can be further reduced to only 45 mW without significant performance degradation. In addition, standby power consumption can be reduced to approximately 25 mW in power-down mode.
The AD9762 is manufactured using an advanced CMOS process. The segmented current source architecture, combined with proprietary switching technology, reduces spurious components and enhances dynamic performance. The device also integrates edge-triggered input latches and a 1.2 V temperature-compensated bandgap reference, providing a complete monolithic DAC solution. Flexible power options support +3 V and +5 V CMOS logic families.
The AD9762 is a current output DAC with a nominal full-scale output current of 20 mA and an output impedance greater than 100 kΩ.
It provides differential current outputs to support single-ended or differential applications. Matching between the two current outputs ensures enhanced dynamic performance in differential output configurations. The current output can be connected directly to an output resistor to provide two complementary single-ended voltage outputs or fed directly into the transformer. The compatible output voltage range is 1.25 V.
The on-chip reference and control amplifier are configured for maximum accuracy and flexibility. The AD9762 can be driven by an on-chip reference or by a variety of different external references. The internal control amplifier provides a wide (>10:1) adjustment range, allowing the full-scale current of the AD9762 to be regulated from 2 mA to 20 mA while maintaining excellent dynamic performance. As a result, the AD9762 can operate at low power levels or be adjusted in the 20 dB range, further providing gain range adjustment.
The AD9762 is available in a 28-lead SOIC package and is specified over the industrial temperature range.
