tle4205g data sheet 6 2015-01-19 circuit description the ic contains two amplifiers with typi cal open-loop gain of 80 db at 500 hz. the input stages consist of pnp-differential amplifiers. this produces a common-mode input range of 0 v to nearly v s and a maximum differential input voltage of v s . the ic is guarded against ground shorts by an soa-prot ective circuit. the output transistors are turned off if the chip te mperature exceeds approx. 160 c. the ic can be turned off by an inhibit input, which very mu ch reduces current consumption. figure 3 circuit diagram 10 k 10 k 10 k 10 k 10 k 200 k 30 k inh gnd +i1 -i1 -i2 +i2 v s q1 q2
