Product Details

The ADA4004-1/ADA4004-2/ADA4004-4 are 1.8 nV/√Hz precision 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 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 1.8 nV/√Hz voltage noise density and a low 6 Hz 1/f noise corner frequency while consuming just 1.7 mA 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 ±5 V to ±15 V from −40°C to +125°C.

The ADA4004-1, ADA4004-2, and ADA4004-4 are members of a growing series of low noise op amps offered by Analog Devices, Inc. (see Table 1).
