We are facing problem in readback of Status register of AD5751.
As per datasheet, reedback of status register data must be clocked out on 5th rising edge of SCLK , but for control register write sequence required data to be clocked on falling edge.
…requirement is 4-20mA output through software mode (through SPI),
Even after done all the setting, not getting the result.
please let me know about the CLEAR pin & CLEARSEL pin in details. How to configure them.
As i set both the bits in control register…
for V to I conversion
AD5751 is a newer device to convert voltage to current outputs
Industrial Current/Voltage Output Driver with Programmable Ranges
Hi winiston.p,
I just remembered that you can also check AD5751 if you only require unipolar output ranges. The specification table is also specified using unipolar supplies.
Cheers,

AD5751也是 电压输入， 4-20mA输出的变送器
你要求的输入时模拟信号，还是数字信号
如果是模拟信号，还可以看一下AD693 AD694
AD420和AD5420是4-20mA输出串行输入DAC，cn0270应用笔记有完整的参考电路。

AD5748、AD5749、AD5750、AD5750-1、AD5751等都可以讲电压输入转换成4-20mA电流输出，cn0203应用笔记有AD5750-1的完整电路。
What do the "ACCURACY (EXTERNAL RSET)" specifications mean for the current outputs of the AD5420, AD5421, AD5750 or AD5755?
