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. 14 OUT D –IN A 2 +IN A 3 V+ 4 +IN B 5 13 –IN D ADA4004-4 TOP VIEW (Not to Scale) 12 +IN D 11 V– 10 +IN C –IN B 6 9 –IN C OUT B 7 8 OUT C 05604-091 GENERAL DESCRIPTION 05604-090 5 –IN B Precision instrumentation Filter blocks Microphone preamplifier Industrial control Thermocouples and RTDs Reference buffers OUT B 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. Rev. A Information furnished by Analog Devices is believed to be accurate and reliable.

Package Type 14-Lead SOIC_N (R-14) 16-Lead LFCSP_VQ (CP-16-4) 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. Rev.
