LMH6624/LMH6626 offer wide bandwidth (1.5GHz for single, 1.3GHz for dual) with very low input noise (0.92nV/ , 2.3pA/ ) and ultra low dc errors (100µV VOS, ±0.1µV/˚C drift) providing very precise operational amplifiers with wide dynamic range. This enables the user to achieve closed-loop gains of greater than 10, in both inverting and non-inverting configurations.
The LMH6624 and LMH6626 are ultra low noise wideband operational amplifiers designed for applications such as instrumentation, ultrasound, and professional audio systems. The LMH6624 is a single-channel device, while the LMH6626 is a dual-channel device. Both offer wide bandwidth with very low input noise and ultra low DC errors, enabling precise operation with closed-loop gains greater than 10.
