AD693 is a voltage-4-20mA current transducer with preset 30-60mV input, 100nRTD input, 4~20mA, O~20rnA non-polar output, and
12t18mA bipolar output .     AD694 is a voltage-4~20mA current transducer with preset 0-2V, O~IOV input, 4~20mA, O~20mA output, and 2.000, 10.OOOV precision reference voltage source. The working power supply is +4.5~+36V. The internal circuit functional block diagram of AD 693/694 is as shown in the figure. They mainly integrate circuits such as amplifiers, reference current sources, reference voltage sources, and voltage- current conversion.
