Rohm is aiming at high-accuracy sensing with a low-noise CMOS op-amp. Accelerometers used in sonar systems and optical sensors are potential applications. LMR1802G-LB achieves input equivalent noise of 2.9nV/√Hz at 1kHz, and 7.8nV/√Hz at 10Hz – according to the firm, it created a new differential input stage circuit to get these figures. It also has 68° ...
