NOTE:
R5 IS A 1% METAL FILM 1/4 W
RESISTOR.
NOTE:
R6 IS A 1% METAL FILM 1/4 W
RESISTOR.
FIGURE 5.
Zero to 1mA current source. The load resistance may be 0 to 20,000 ohms. Other values of full scale current may be set by changing R5. The maximum
output current is determined by 0.8V/(R5+50) and is limited to 20 mA.
FIGURE 6.
Shows a voltage to voltage transmitter. Note that this configuration will have a 249 ohm output source resistance which will produce an error of 2.5%
if driving a 10,000 ohm load or 0.25% if driving a 100,000 ohm load. R6 parallels the internal 50 ohms to produce 20mA output with full scale input.
There will be 0.8 Volts between pins 7 and 4 with full scale input.
