techni cal data 2011, january, rev. 0 1 low power quad operational amplifier the il2902 contains four independent high gain operational amplifiers with internal frequen cy compensation. the four op - amps operate over a wide voltage range from a single power supply. also use a split power supply. the device has low power supply current drain, regardless of the power supply voltage. the low power drain also makes the il2902 a good choice for battery operation. when your project calls for a traditional op - amp function, now you can streamline your design with a simple single power supply. use ordinary +5v dc common to practically any digital system or personal computer applicati on, without requiring an extra 15v power supply just to have the interface electronics you need. the il2902 is a versatile, rugged workhorse with a thousand - and - one uses, from amplifying signals from a variety of transducers to dc gain blocks, or any op - am p function. the attached pages offer some recipes that will have your project cooking in no time. ? internally frequency compensated for unity gain ? large dc voltage gain: 100db ? wide power supply range: 3v ~ 32v (or 1.5v ~ 16v) ? input common - mode voltage ra nge includes ground ? large output voltage swing: 0v dc to v cc - 1.5v dc ? power drain suitable for battery operation ? low input offset voltage and offset current ? differential input voltag e range equal to the power supply voltage il2902 ordering information il2902 n plastic il2902 d soic t a = - 40 to +85 c for all packages . logic diagram pin 4 = v cc pin 11= gnd pin assignment
