Notes
1. At Tj = 125 °C. The temperature coefficient of Vloss has a positive sign.
2. The linearity error is measured without S correction and based on the same measurement principle as performed on
the screen. The measuring method is as follows:
Divide the output signal into 22 equal time parts ranging from 1 to 22 inclusive. Measure the value of the voltage
across RM of two succeeding parts called one block (a) starting with part 2 and 3 (block 1) and ending with
part 20 and 21 (block 10). Thus parts 1 and 22 are unused. The equations for linearity error for adjacent blocks
(LEAB) and not adjacent blocks (LENAB) are given below:
3. Vo(A) +Vo(B) =VP. At the start of the scan this equation is one diode voltage less.
4. The V value within formulae relates to voltages at or between relative pin numbers, i.e. V9to5/V3to5 = voltage value
across pins 9 and 5 divided by voltage value across pins 3 and 5.
5. V2to5 AC short-circuited.
6. At V(ripple) = 500 mV (eff) at VP; measured across RM; f(ripple) =50Hz 1 kHz.
7. Ii(bias) +Ii(diff) ≤ 800 A and Ii(bias) Ii(diff) ≥ 50 A per pin.
