Quick reference data [1] With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal to the DC output offset voltage divided by RL. [2] Power supply rejection ratio is measured at the output with a source impedance of RS =0 Ω at the input. The ripple voltage is a sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail. [3] Power supply rejection ratio is measured at the output, with a source impedance of RS =0 Ω at the input. The ripple voltage is a sine wave with a frequency between 100 Hz and 20 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail. 5. Ordering information Table 1.
