1.8 nV/√Hz, 36 V Precision Quad Amplifier ADA4004-4 FEATURES Very low voltage noise: 1.8 nV/√Hz Low input bias current: 100 nA maximum Offset voltage: 100 μV maximum High gain: 120 dB Wide bandwidth: 12 MHz ±5 V to ±15 V operation PIN CONFIGURATIONS OUT A OUT D 14 NC 16 15 –IN A 1 +IN A 2 VCC 3 +IN B 4 NC 13 12 –IN D ADA4004-4 TOP VIEW (Not to Scale) 11 +IN D 10 VEE 9 +IN C APPLICATIONS Precision instrumentation Filter blocks Microphone preamplifier Industrial control Thermocouples and RTDs Reference buffers 5 6 7 8 OUT B OUT C –IN B –IN C NC = NO CONNECT Figure 1. 16-Lead LFCSP (CP-16-4 Suffix) OUT A 1 14 OUT D 13 –IN D 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 iPolar™ 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, 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 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. –IN A 2 +IN A 3 V+ 4 +IN B 5 –IN B 6 OUT B 7 ADA4004-4 TOP VIEW (Not to Scale) 12 +IN D 11 V– 10 +IN C 05577-091 9 8 –IN C OUT C Figure 2. 14-Lead SOIC (R-14 Suffix) Rev.
