ADI ADA4004-2ARZ

The ADA4004-1/ADA4004-2/ADA4004-4 are 1.8nV/√Hz precision amplifiers featuring 40μV offset, 0.7μV/°C drift, 12MHz bandwidth, and low 1.7mA per amplifier supply current. The ADA4004-1/ADA4004-2/ADA4004-4 are 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 6Hz 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. Operation is fully specified from ±5V to ±15V from -40°C to +125°C
