Input 1-5V DC, the output becomes 4-20mA, the external circuit is required to be simple, the amplifier SR value is high, the CMRR value is high, the PSRR value is high, and the most important thing is that the amplifier itself integrates a bridge. Please give me a model.
I only input the signal all the way, and it is best not to use the programmable gain, my gain is fixed.
