OUT A 1
The ADA4004-4 is a 1.8 nV/√Hz precision quad amplifier in a
16 mm2 LFCSP_VQ package featuring 40 μV offset, 0.7 μV/ºC
drift, 12 MHz bandwidth, and low 1.7 mA/amplifier supply
current.
The ADA4004-4 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
ADA4004-4 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/amplifier. The small package saves board space, reduces
cost, and improves layout flexibility.

APPLICATIONS
Figure 2. 14-Lead SOIC_N
(R-14 Suffix)
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, 4 mm × 4 mm LFCSP_VQ and the 14-lead, narrow
SOIC_N, lead-free, surface-mount packages. Operation is fully
specified from ±5 V to ±15 V from −40°C to +125°C.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in circuit board for surface-mount packages.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
