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?
What is the effect of my reference's variation on the output of my AD5421?
