GENERAL DESCRIPTION
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).
