PUMPING COMPENSATION The device incorporates a special preampliflier, the gain of which varies with changes in supply voltage. This functionallows perfect compensationof height variations caused by changes in brightness. 2/3 TDA8175 PACKAGE MECHANICAL DATA :9 PINS - PLASTIC HEPTAWATT L E L1 M1 A C D1 L2 L5 L3 G1 H3 Dia.
