Referenced to lower amplitude tone. 2. Bandwidth limited (0 to 3.4 kHz) Gaussian Noise. This device contains circuitry to protect the inputs against damage due to high static volt- ages or electric fields; however, it is advised that normal precautions be taken to avoid applica- tions of any voltage higher than the maximum rated voltages to this high impedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Reliability of operation is enhanced if unused inputs are tied to and appropriate logic voltage level (e.g., either VSS or VDD). |
