this extremely versatile operational amplifier features low power consumption and high input impedance. in addition, the quiescent currents within the device may be programmed by the choice of an external resistor value or current source applied to the i set input. this allows the amplifier's characteristics to be optimized for input current and power consumption despite wide variations in operating power supply voltages. ? 1.2 v to 18 v operation ? wide programming range ? offset null capability ? no frequency compensation required ? low input bias currents ? short circuit protection resistive programming (see figure 1) r set to ground r set to negative supply active programming fet current source bipolar current source (recommended for supply voltage less than 6.0 v) typical r set values v cc , v ee i set = 1.5 m ai set = 15 m a 6.0 v 10 v 12 v 15 v 3.6 m w 6.2 m w 7.5 m w 10 m w 360 k w 620 k w 750 k w 1.0 m w pins not shown are not connected. typical r set values v cc , v ee i set = 1.5 m ai set = 15 m a 1.5 v 3.0 v 6.0 v 15 v 1.6 m w 3.6 m w 7.5 m w 20 m w 160 k w 360 k w 750 k w 2.0 m w v cc 0.6 r set i set = 7 2 3 4 8 + r set v ee i set = v cc 0.6 v ee r set + 2 3 7 6 4 8 v ee v g v ee 7 2 3 4 8 6 v ee r v b v ee q + 6 v cc v cc 7 2 3 4 8 + r set v ee 6 v cc ? motorola, inc. 1996 rev 5
