The MXL1013/MXL1014 is a high-precision dual/quad op amp from Maxim with a typical offset voltage of 40µV, 0.3µV/°C drift and 117dB CMRR and 120dB PSRR.
The MXL1013 is a precision dual op‑amp and the MXL1014 is a precision quad op‑amp that replace legacy devices such as the MC1458, MC1558, LM158, OP221, LT1013 and LT1014. Both devices operate from a single +5 V supply, accept input voltages down to ground, and can source or sink more than 20 mA.
The document lists detailed electrical characteristics, absolute maximum ratings, package options, and ordering codes. It also includes typical operating curves, noise spectra, and pin‑out diagrams for the various DIP, SO and CERDIP packages.
| Input Offset Voltage | 40 µV (typ) |
|---|---|
| CMRR | 117 dB |
| Supply Current per Amplifier | 0.35 mA (typ) |
| Maximum Supply Current per Amplifier | 500 µA |
Both the MXL1013 and the MXL1014 can be operated from a single +5 V power supply.
They are used in battery‑powered precision instrumentation, strain‑gauge signal conditioners, thermocouple amplifiers, instrumentation amplifiers, 4‑20 mA current‑loop transmitters, multiple‑limit threshold detection, active filters, and multiple gain blocks.
The MXL1013 is offered in 8‑pin plastic DIP, 8‑pin SO, 14‑pin CERDIP, and 16‑pin wide SO packages with various temperature ranges.
The maximum supply current per amplifier is 500 µA.
