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.
The LT1013 and LT1014 are precision operational amplifiers from Linear Technology. The LT1013 is a dual‑op‑amp in an 8‑pin DIP package, while the LT1014 is a quad‑op‑amp that fits the same pin‑out as the LM324/LM348 family. Both devices operate from a single 5 V supply, provide low offset voltage, low bias current and high gain, and are suitable for battery‑powered instrumentation, current‑loop transmitters, active filters and many other precision circuits.
The document provides detailed electrical characteristics, absolute maximum ratings, package dimensions, and typical performance graphs. It also includes example applications such as a three‑channel thermocouple thermometer and a step‑up switching regulator for a 6 V battery, together with recommended PCB layout and solder‑pad guidelines.
| Input Offset Voltage (typical) | 150 µV (LT1013), 180 µV (LT1014) |
|---|---|
| Input Bias Current (typical) | 0.8 nA (LT1014), 0.15 nA (LT1013) |
| Supply Current per Amplifier | 500 µA max |
| Large Signal Voltage Gain | ≈8 million |
| Output Swing | Can swing to ground while sinking current |
They are fully specified for single‑supply operation with the negative supply at 0 V; the input common‑mode range includes ground and the output can swing within a few millivolts of ground.
The LT1013 guarantees a maximum offset voltage of 150 µV, while the LT1014 typical offset voltage is 180 µV.
Each amplifier draws up to 500 µA of supply current.
