When you're measuring the voltage at Iout, you should do it across an RL, a typical value here is 500 ohm.
Can you send scope shots of your voltage measurements?
I am using a AD5420 how in image
, but the output is always constant. In code, I send the next words:
LATCH = 0;
delay of 100ns
01010101 -adress byte (control register)
00010000 - control register
00000101 - define mode 4 to 20mA
Will the AD5420 performance meet the specifications under the following conditions?
External Reference 5V
( Can the External Reference be more than the digital supply? )
Hello. I am consulting for a client based in US. We have designed a device for them that is based on a D/A converter (AD5420), which is supposed to output a 4~20 mA signal to a variable valve to regulate pressure and flow.
Electronically, I am using…
I'm using AD5420 in above mentioned configuration. I've interfaced AD5700-1 HART modem with AD5420.
I'm providing Hart out from modem to CAP2 pin not RSET. RSET pin is just having 15K resistor to ground which is not shown here.
I tried to use the following schematic to set AD5420 working in daisy-chain mode.
When the print circuit board was produced, I wrote driver code to make it work. It seems that the dirver can work properly, because the content of Control Register, readed…
