ad5737四通道12位串行输入4毫安到20毫安的输出具有动态功率控制和HART连接的DAC数据表

　　The AD5737 is a quad-channel current output DAC that operates with a power supply range from 10.8 V to 33 V. On-chip dynamic power control minimizes package power dissipation by regulating the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation. Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5737. The AD5737 uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI， QSPI™， MICROWIRE®， DSP， and microcontroller interface standards. The serial interface also features optional CRC-8 packet error checking， as well as a watchdog timer that monitors activity on the interface.
