GENERAL DESCRIPTION
The ADA4004-4 is a 2nV/Hz precision quad amplifier in a
16mm LFCSP package featuring 40V offset, 0.7V/C
drift, 12MHz bandwidth and low 1.7mA/amp supply current.
The ADA4004-4 is designed on the high performance
iPolarTM 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 2nV/Hz voltage noise density,
and a low 6Hz 1/f noise corner frequency while consuming
just 1.7mA/amp. 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 ADA4004-4 is offered in the very
small 16-lead, 4mm X 4mm LFCSP and 14-lead narrow
SOIC lead-free, surface mount packages. Operation is fully
specified from 5V to 15V from -40C to +125 C.
