... Figure 3. Burn-In Circuit APPLICATIONS INFORMATION Voltage and Current Noise The OP471 is a very low-noise quad op amp, exhibiting a typical voltage noise of only 6 kHz. The low noise character- istic of the OP471 is, in part, achieved by operating the input transistors at high collector currents since the voltage noise is inversely proportional to the square root of the collector current ...
