GENERAL DESCRIPTION
The ADA4004-4 is a 1.8 nV/√Hz precision quad amplifier in a
16-lead, 4 mm × 4 mm LFCSP package featuring 40 μV offset,
0.7 μV/°C drift, 12 MHz bandwidth, and low 1.7 mA per
amplifier supply current.
The ADA4004-4 is designed on the high performance i
process, enabling improvements such as reduced noise and
power consumption, increased speed and stability, and smaller
footprint size. Novel design techniques enable the 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,
LL filters, high performance precision filters, medical and
P
analytical instrumentation, precision power supply controls,
ATE, and data acquisition systems.
The high performance ADA4004-4 is offered in the very small
16-lead
, 4 mm × 4 mm LFCSP and the 14-lead, narrow SOIC,
RoHS compliant, surface-mount packages. Operation is fully
specified from ±5 V to ±15 V from −40°C to +125°C.
