1 / 24 page  1 LT1013/LT1014 10134fc Quad Precision Op Amp (LT1014) Dual Precision Op Amp (LT1013) The LT ®1014isthefirstprecisionquadoperationalamplifier 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 LT1014’s low offset voltage of 50 μV, drift of 0.3μV/°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 μA 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 LT1013’s specifications are similar to (even somewhat better than) the LT1014’s. 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. ■ Single Supply Operation Input Voltage Range Extends to Ground Output Swings to Ground while Sinking Current ■ Pin Compatible to 1458 and 324 with Precision Specs ■ Guaranteed Offset Voltage: 150 μV Max ■ Guaranteed Low Drift: 2 μV/°C Max ■ Guaranteed Offset Current: 0.8nA Max ■ Guaranteed High Gain 5mA Load Current: 1.5 Million Min 17mA Load Current: 0.8 Million Min ■ Guaranteed Low Supply Current: 500 μA Max ■ Low Voltage Noise, 0.1Hz to 10Hz: 0.55 μVp-p ■ Low Current Noise—Better than 0P-07, 0.07pA/ √Hz ■ Battery-Powered Precision Instrumentation Strain Gauge Signal Conditioners Thermocouple Amplifiers Instrumentation Amplifiers ■ 4mA–20mA Current Loop Transmitters ■ Multiple Limit Threshold Detection ■ Active Filters ■ 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 Ω AT 25 °C 260 Ω 1684 Ω 299k 3k LT1004 1.2V 14 12 13 – + LT1014 USE TYPE K THERMOCOUPLES.
