MIL-M-38510/110C
NOTES:
1/ All resistors ±0.1 percent tolerance and all capacitors are ±10 % tolerance.
2/ Precautions shall be taken to prevent damage to the device under test during insertion into socket and change of state of relays (i.e. disable voltage supplies, current limit ±VCC, etc.).
3/ Stabilizing capacitors may be added as required, if needed to prevent oscillations. Also, proper wiring procedures shall be followed to prevent oscillations. Loop response and settling time shall be consistent with the test rate such that any value has settled for at least five loop time constants before the value is measured, however, adequate settling time shall be allowed such that each parameter has settled to within five percent of its final value. There are two general methods to stabilize the test circuit: One method is with a capacitor in the nulling amplifier feedback loop and the other method is with a capacitor in parallel with the 49.9 kν closed loop feedback resistor. Both methods shall not be used simultaneously.
4/ All relays are shown in the normal de-energized state. Relays K1, K2, K3, and K4 select amplifiers A, B, C, and
D respectively. The rest of the relays are used to select the conditions for each test.
5/ Each amplifier shall be tested separately, except for the ICC measurements where all the amplifiers shall be connected as grounded followers (relays K1 through K4 de-energized).
6/ The nulling amplifier should be an M38510/11001XXXor similar. Saturation of the nulling amplifier is not allowed on test where the E (pin 5) value is measured.
7/ The load resistors 2,050 ν and 11.1 kν yield effective load resistances of 2 kν and 10 kν, respectively.
8/ Any oscillation greater that 300 mV in amplitude (peak - peak) shall be a cause for device failure.
