  Lars Lotzenburger

  HI Shinu, thanks for contacting us via e2e regarding this customer inquiry. Please find my answers below. 1) An open circuit is detected by reading 0V (due to 0mA) from the shunt. This violates the requirement of having at least a 4mA current and can be…

  Hi U-SK, U-SK said: Is my following understanding correct? -> In TIDA1504, it might be possible that MSP430FR2355 work as DAC8740H + DAC8830 + OPA333 + OPA335 Are there any possible problems? In theory, that is correct; however, TIDA-01504 is mostly…

  Hi keiven, The HART physical layer test is a system level test of the end product (transmitter, analog input module, etc). Of course, the DAC874xH was designed to meet the HART physical layer standard, but it is not an IC level test. We have a transmitter…
