APPLICATION INFORMATION
Fig.23 Application and timing for feedback mode.
For f < 50 kHz and C2 < 47 nF calculation formulas and behaviour of the OTA are the same as for an OP. An exception is the limited output current at
BOP (pin 3). See Chapter “Characteristics”, Row Head “B+ control section; see Figs 23 and 24”.
(1) The recommended value for R6 is 1 k
.
a. Feedback mode application.
b. Waveforms for normal operation.
c. Waveforms for fault condition.
