Figure 3. 8-Lead MSOP (RM-8) and 8-Lead SOIC (R-8) The ADA4004-1/ADA4004-2/ADA4004-4 are designed on the OUT A 1 14 OUT D high performance iPolar process, enabling improvements such IN A 2 13 IN D as reduced noise and power consumption, increased speed and 3 12 +IN A ADA4004-4 +IN D stability, and smaller footprint size. Novel design techniques enable V+ 4 TOP VIEW 11 V (Not to Scale) 5 10 the ADA4004-1/ADA4004-2/ADA4004-4 to achieve 1.8 nV/Hz +IN B +IN C IN B 6 9 IN C voltage noise density and a low 6 Hz 1/f noise corner frequency 7 8 OUT B OUT C while consuming just 1.7 mA per amplifier. The small package Figure 4. 14-Lead SOIC saves board space, reduces cost, and improves layout flexibility. (R-14) 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. Operation is fully specified IN A 1 IN D 12 from 5 V to 15 V from 40C to +125C. +IN A 2 11 +IN D ADA4004-4 TOP VIEW The ADA4004-1, ADA4004-2, and ADA4004-4 are members V+ 3 10 V (Not to Scale) of a growing series of low noise op amps offered by Analog +IN B 4 9 +IN C Devices, Inc., (see Table 1).
