GENERAL DESCRIPTION
The ADA4004-1 and ADA4004-2 are single and dual precision
bipolar op amps that featuring a 1.8 nV/√Hz precision, 40 μV
offset, 0.7 μV/ºC drift, 12 MHz bandwidth, and low 1.7
mA/amplifier supply current.
The ADA4004 is designed on the high performance iPolar™
process, enabling improvements such as reduced noise and
power consumption, increased speed and stability, and a
smaller footprint size. Novel design techniques enable the
ADA4004 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/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.
The high performance ADA4004 is offered in the very small 5-
lead SOT and 8-lead SOIC for the single (ADA4004-1) and the
8-lead MSOP for the dual (ADA4004-2), lead-free, surface-
mount packages. Operation is fully specified from ±5 V to ±15
V from −40°C to +125°C.
