The ADA4004-4 is designed on the high performance iPolar™ process, enabling improvements such as reduced noise and power consumption, increased speed and stability, and a smaller footprint size. Novel design techniques enable the ADA4004-4 to achieve 1.8 nV/√Hz voltage noise density and a low 6 Hz 1/f noise corner frequency while consuming just 1.7 mA/amplifier. The small package saves board space, reduces cost, and improves layout flexibility. Applications for these amplifiers include high precision controls, PLL filters, high performance precision filters, medical and analytical instrumentation, precision power supp...
