Notes
1. To limit V
2. Allowable input range: V
3. This value specifies the sum of the voltage losses of the internal current paths between pins V
4. This value specifies the sum of the voltage losses of the internal current paths between pins V
5. The linearity error is measured for a linear input signal without S-correction and is based on the ‘on screen’
6. The linearity errors are specified for a minimum input voltage of 300 mV (p-p). Lower input voltages lead to voltage

10. V
11. This value specifies the internal voltage loss of the current path between pins V

measurement principle. This method is defined as follows. The output signal is divided in 22 successive equal time
blocks k. The 1st and 22nd blocks are ignored, while the voltage amplitudes are measured across R
