GENERAL DESCRIPTION
The ADA4004-4 is a 1.8 nV/Hz precision quad amplifier in a 16 mm2 LFCSP_VQ package featuring 40 V offset, 0.7 V/C drift, 12 MHz bandwidth, and low 1.7 mA/amplifier 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 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 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 x 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 -40C to +125C.

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
JA is specified for the worst-case conditions, that is, a device soldered in circuit board for surface-mount packages. Table 4.

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.
