loop voltage of 80V, Q1 will dissipate 1.6W when I

Figure 5 shows how to use an LTC2630HZ to make an

optoisolated, digitally-controlled 4mA to 20mA transmit-

ter. The transmitter circuitry, including optoisolation, is

5.4V to 80V. The 5V output of the LT^®3010-5 is used to

set the 4mA offset current and V

control the 0mA to 16mA signal current. The supply cur-

rent for the regulator, DAC, and op amp is well below
