ADA4004-1ARZ-R7

ADA4004-1ARZ-R7 is a 1.8nV/√Hz, 36V precision amplifier. It is designed on the high performance iPolar™ process, enabling improvements such as reduced noise and power consumption, increased speed and stability, and smaller footprint size. Novel design techniques enable the ADA4004-1/ADA4004-2/ADA4004-4 to achieve 1.8nV/√Hz voltage noise density and a low 6 Hz 1/f noise corner frequency while consuming just 1.7mA per 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 supply controls, ATE, and data acquisition systems. Also used in precision instrumentation, filter blocks, microphone preamplifiers, industrial control, thermocouples and RTDs, reference buffers.
