The MXD8116LE is a low-noise 12V ultra-low-power operational amplifier with rail-to-rail inputs and outputs, manufactured by Maxscend. It is a 14-pin quad op-amp packaged in a quad small footprint (QFN-14) with a low-noise level of 1.2µV in a 10Hz bandwidth. It is RoHS compliant and has a very low 0.19mA quiescent current per amplifier. Its low operating voltage ranges from 1.8V to 12V, making it suitable for most application conditions. The MXD8116LE also has excellent common mode rejection ratio (CMRR) as well as a high supply rejection ratio (PSRR) for improved signal accuracy. Moreover, the amplifier is capable of providing a well-defined response with an output slew rate of 1.3mV/µs and a unity-gain bandwidth of 7MHz.
