ROHM - New CMOS Op-Amp delivers leading-class low noise (LMR1802G-LB)

ROHM has added an operational amplifier with the industry's best performance in terms of external noise optimized for consumer and industrial equipment. Compared with the company's traditional products, the LMR1802G-LB is developed using the company's analog technology, covering circuit design, process and layout, which can reduce the input equivalent noise voltage density by half (2.9nV / √Hz at 1kHz, and 7.8nV / √Hz), which greatly improves the detection performance of the sensor signal. Similarly, the best-in-class phase margin (68 degrees) and capacitive load tolerance (500pF) provide excellent stability (difficult to oscillate and easy to handle). In this way, the voltage can be accurately amplified to about μV, thereby ensuring support for applications requiring high-precision sensing. This device is ideal for applications that require high-precision sensing, including sonar and optical sensors.
