ROHM has recently announced the availability of a CMOS op-amp featuring the lowest noise in the industry optimized for industrial applications requiring high-accuracy sensing, such as accelerometers used in sonar systems, and optical sensors that handle ultra-small signals.
The LMR1802G-LB, developed utilizing ROHM’s analog technology covering circuit design, processes, and layout, reduces input equivalent noise voltage density by half (2.9nV/√Hz at 1kHz, 7.8nV/√Hz at 10Hz) compared to conventional products, significantly improving the detection performance of sensor signals. In addition, best-in-class phase margin (68°) and capacitive load tolerance (500pF) provide excellent stability (difficult to oscillate, easy to handle). This enables accurate amplification of voltages in the order of µV, ensuring support for industrial and consumer applications requiring high-precision sensing.
The LMR1802G-LB offers an input offset voltage of 450µV and input bias current of only 0.5pA (4x and 2x less than conventional products, respectively), providing high accuracy amplification (more info).
