With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being equal to the DC output offset voltage divided by RL. 2. The noise output voltage (Vn(o)(rms)) at f = 500 kHz, is measured with Rs = 0 Ω and B = 5 kHz. 3. The ripple rejection is measured with Rs = 0 Ω and f = 100 Hz to 10 kHz. The ripple voltage (Vripple = 200 mV RMS) is applied to the positive supply rail. 4. The noise output voltage (Vn(o)(rms)) is measured with Rs = 5 kΩ unweighted. 1998 Feb 23 6 Document Outline Features General description Quick reference data Ordering information Block diagram Pinning Functional description Power dissipation Limiting values Thermal characteristics Characteristics Test and application information Test conditions Voltage gain Output power Switch-on/switch-off Thermal behaviour: Short-circuit protection: Package outline Soldering Introduction Reflow soldering Wave soldering Repairing soldered joints Data sheet status Disclaimers
