1 LT1013/lt1014 quad precision op amp (lt1014) dual precision op amp (LT1013) the lt ? 1014 is the first precision quad operational amplifier which directly upgrades designs in the industry standard 14-pin dip lm324/lm348/op-11/4156 pin configuration. it is no longer necessary to compromise specifications, while saving board space and cost, as compared to single operational amplifiers. the lt1014s low offset voltage of 50 m v, drift of 0.3 m v/ c, offset current of 0.15na, gain of 8 million, common-mode rejection of 117db and power supply rejection of 120db qualify it as four truly precision operational amplifiers. particularly important is the low offset voltage, since no offset null terminals are provided in the quad configura- tion. although supply current is only 350 m a per amplifier, a new output stage design sources and sinks in excess of 20ma of load current, while retaining high voltage gain. similarly, the LT1013 is the first precision dual op amp in the 8-pin industry standard configuration, upgrading the performance of such popular devices as the mc1458/ 1558, lm158 and op-221. the LT1013s specifications are similar to (even somewhat better than) the lt1014s. both the LT1013 and lt1014 can be operated off a single 5v power supply: input common-mode range includes ground; the output can also swing to within a few millivolts of ground. crossover distortion, so apparent on previous single-supply designs, is eliminated. a full set of specifi- cations is provided with 15v and single 5v supplies. features descriptio n u n single supply operation input voltage range extends to ground output swings to ground while sinking current n pin compatible to 1458 and 324 with precision specs n guaranteed offset voltage 150 m v max. n guaranteed low drift 2 m v/ c max. n guaranteed offset current 0.8na max. n guaranteed high gain 5ma load current 1.5 million min. 17ma load current 0.8 million min. n guaranteed low supply current 500 m a max. n low voltage noise, 0.1hz to 10hz 0.55 m vp-p n low current noisebetter than 0p-07, 0.07pa/ ? hz applicatio n s u n battery-powered precision instrumentation strain gauge signal conditioners thermocouple amplifiers instrumentation amplifiers n 4maC20ma current loop transmitters n multiple limit threshold detection n active filters n multiple gain blocks + lt1014 1 4 11 2 3 +5v +5v 1m 4k output a 10mv/ c + lt1014 7 6 5 1m output b 10mv/ c 4k 1.8k ysi 44007 5k at 25 c 260 1684 299k 3k lt1004 1.2v 14 12 13 + lt1014 use type k thermocouples. all resistors = 1% film. cold junction compensation accurate to 1 c from 0 c 60 c. use 4th amplifier for output c. lt1014 distribution of offset voltage 3 channel thermocouple thermometer input offset voltage ( v) 300 0 200 200 100 100 300 number of units 700 600 500 400 300 200 100 0 v s = 15v t a = 25 c 425 lt1014s (1700 op amps) tested from three runs j package , ltc and lt are registered trademarks of linear technology corporation.
