ADA4004-1ARZ-RL GENERAL DESCRIPTION

The ADA4004-1/ADA4004-2/ADA4004-4 are 1.8 nV/√Hzprecision amplifiers featuring 40 μV offset, 0.7 μV/°C drift,12 MHz bandwidth, and low 1.7 mA per amplifier supply current.The ADA4004-1/ADA4004-2/ADA4004-4 are designed on thehigh performance iPolar™ process, enabling improvements suchas reduced noise and power consumption, increased speed andstability, and smaller footprint size. Novel design techniques enablethe ADA4004-1/ADA4004-2/ADA4004-4 to achieve 1.8 nV/√Hzvoltage noise density and a low 6 Hz 1/f noise corner frequencywhile consuming just 1.7 mA per amplifier. The small packagesaves board space, reduces cost, and improves layout flexibility.Applications for these amplifiers include high precision controls,PLL filters, high performance precision filters, medical andanalytical instrumentation, precision power supply controls,ATE, and data acquisition systems. Operation is fully specifiedfrom ±5 V to ±15 V from −40°C to +125°C.The ADA4004-1, ADA4004-2, and ADA4004-4 are membersof a growing series of low noise op amps offered by AnalogDevices, Inc., (see Table 1).Table 1.
