Charge_injection_tests

Figure 2-V shows a test circuit for measuring charge injection for the MAX301/ 3/5. Notice that charge injection (Q) is measured in coulombs (C). A pulse is applied to the control pin and the difference in output voltage is noted. Q is calculated when the difference in output voltage is divided by the capacitance at the output. Typical charge injection is 10 to 15pC.
