Product Description

AD5751是一款单通道、低成本、高精度、电压/电流输出驱动器，输出范围可通过硬件或软件编程。软件输出范围可通过SPI/Microwire兼容串行接口进行设置。AD5750可满足PLC和工业过程控制应用。AD5750的模拟输入由低电压、单电源数模转换器提供，对该模拟输入进行调理以提供所需的输出电流/电压范围。

AD5751提供五种可编程输出电流范围：4～20 mA、0～20 mA或0～24 mA、±20 mA和±24 mA；通过配置单独的引脚可以提供四种输出电压范围：0 V～5 V、0 V～10 V、±5 V或±10 V。AD5750可以提供20%的超额输出电压。

AD5751的模拟输出具有短路和开路保护功能，可以驱动1uF的电容负载和0.1H的电感负载。该器件的工作电压范围是±12 V～±24 V。输出环路电压范围是0 V～AVDD-2.5 V。

AD5751采用灵活的SPI串行接口并且兼容MICROWIRE，可以在3线模式下工作，以获得隔离应用中要求的最小的数字隔离。而且，该接口使用CRC-8纠错方案，具有可选择的PEC纠错功能，适用于可能发生数据通信故障的工业环境。

AD5751还具有上电复位功能，用于确保器件在已知状态下上电，并且具有异步CLEAR引脚，用于将输出电压设置为零电位/中间电位，或者是选定电流范围的下限值。

HW SELECT引脚用于在上电时将器件编程模式配置为硬件编程或软件编程。

在电流模式和电压模式下，总输出误差的典型值均为±0.1%。
