The current output circuit was
measured in 0-mA to 24-mA mode using an 8.5 digit digital multi-meter to measure the
output while driving a 300-Ω load at 25°C. The measured results are shown in Figure 9-8. The voltage output circuit was measured in ±10-V mode using an 8.5 digit digital
multi-meter to measure the output while driving a
1-kΩ load at 25°C. The measured results are shown in Figure 9-9. In both cases, the voltage and current outputs remain within the specified performance of the data sheet.
The design was also exposed to IEC61000-4 electrostatic discharge, electrically fast transient, conducted immunity, and radiated immunity tests on both the current and voltage outputs. During each of these tests a 6.5 digit digital multi-meter, set in fast 5.5 digit acquisition mode, was used to monitor the outputs. Complete data sets for the voltage and current outputs during these tests are available in TIPD153.
