9 / 60 page TDA9112A 9/60 6 ELECTRICAL PARAMETERS AND OPERATING CONDITIONS Medium (middle) value of an I²C-bus control or adjustment register composed of bits D0, D1,...,Dn is the one having Dn at "1" and all other bits at "0". Minimum value is the one with all bits at 0, maximum value is the one with all at "1". Currents flowing from the device (sourced) are signed negative. Currents flowing to the device are signed positive. TH is period of horizontal deflection. 6.1 Thermal data 6.2 Supply and Reference voltages Tamb = 25°C 6.3 Synchronization inputs Vcc = 12V, Tamb = 25°C Symbol Parameter Value Unit Min. Typ. Max.
