Manufacturer:TI Description:TEST CIRCUIT A complete schematic diagram of the test circuit is shown in Figure 7 The test circuit accepts the outputs of the power supplies and function generator and provides horizontal and vertical outputs for an X-Y oscilloscope which is used as the measurement system The primary elements of the test circuit are the feedback buffer and integrator comprising amplifier A7 and its feed- back network C16 R31 R32 and C17 and the differential amplifier network comprising the device under test and the feedback network R40 R43 R44 and R52 The remainder of the test circuit provides the proper conditioning for the de- vice under test and scaling for the oscilloscope on which the test results are displayed The amplifier A8 provides a variable amplitude source of common mode signal to exercise the amplifier under test over its common mode range This amplifier is connected as a non-inverting gain-of-3 6 amplifier and receives its input from the triangular wave generator Potentiometer R37 al- lows the output of this amplifier to be varied from g0 volts to g18 volts The output of this amplifier drives the differen- tial input resistors R43 and R44 for the device under test The resistors R46 and R47 are current sensing resistors which sense the input current of the device under test These resistors are switched into the circuit in the proper sequence by the field effect transistors Q6 and Q7 Q6 and Q7 are driven from the square wave output of the function generator by the PNP pair Q10 and Q11 and the NPN pair Q8 and Q9 Switch sections S1b and S1c select the switch- ing sequence for Q8 and Q9 and hence for Q6 and Q7 In the bias current test the FET drivers Q8 and Q9 are switched by out of phase signals from Q10 and Q11 This opens the FET switches Q6 and Q7 on alternate half cycles of the square wave output of the function generator During the offset voltage offset current test the FET drivers are |
