LT1013/LT1014 Quad Precision Op Amp (LT1014) Dual Precision Op Amp (LT1013)
FeaTures DescripTion
n Single Supply Operation The LT®1014 is the first precision quad operational amplifier Input Voltage Range Extends to Ground which directly upgrades designs in the industry standard Output Swings to Ground While Sinking Current 14-pin DIP LM324/LM348/OP-11/4156 pin configuration. n Pin Compatible to 1458 and 324 with Precision Specs It is no longer necessary to compromise specifications, n Guaranteed Offset Voltage: 150µV Max while saving board space and cost, as compared to single n Guaranteed Low Drift: 2µV/°C Max operational amplifiers. n Guaranteed Offset Current: 0.8nA Max The LT1014’s low offset voltage of 50µV, drift of 0.3µV/°C, n Guaranteed High Gain offset current of 0.15nA, gain of 8 million, common mode 5mA Load Current: 1.5 Million Min rejection of 117dB and power supply rejection of 120dB 17mA Load Current: 0.8 Million Min qualify it as four truly precision operational amplifiers. n Guaranteed Low Supply Current: 500µA Max Particularly important is the low offset voltage, since no n Low Voltage Noise, 0.1Hz to 10Hz: 0.55µVP-P offset null terminals are provided in the quad configura- Low Current Noise—Better than 0P-07, 0.07pA/√Hz tion. Although supply current is only 350µA per amplifier, a new output stage design sources and sinks in excess of 20mA of load current, while retaining high voltage gain.
applicaTions
Similarly, the LT1013 is the first precision dual op amp n Battery-Powered Precision Instrumentation in the 8-pin industry standard configuration, upgrading Strain Gauge Signal Conditioners the performance of such popular devices as the MC1458/ Thermocouple Amplifiers MC1558, LM158 and OP-221. The LT1013’s specifications Instrumentation Amplifiers are similar to (even somewhat better than) the LT1014’s. n 4mA to 20mA Current Loop Transmitters n Multiple Limit Threshold Detection Both the LT1013 and LT1014 can be operated off a single n Active Filters 5V power supply: input common mode range includes n Multiple Gain Blocks ground; the output can also swing to within a few millivolts L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear of ground.
