(Not to Scale)  
The AD8671/AD8672/AD8674 are very high precision amplifiers  
featuring very low noise, very low offset voltage and drift, low  
input bias current, 10 MHz bandwidth, and low power

consumption. Outputs are stable with capacitive loads of over  
Figure 5. 14-Lead SOIC_N (R-14)  
Figure 6. 14-Lead TSSOP (RU-14)  
1000 pF. Supply current is less than 3 mA per amplifier at 30 V.  
The AD8671/AD8672/AD8674’s combination of ultralow noise,  
high precision, speed, and stability is unmatched. The MSOP  
version of the AD8671/AD8672 requires only half the board  
space of comparable amplifiers.  
Applications for these amplifiers include high quality PLL  
filters, precision filters, medical and analytical instrumentation,  
precision power supply controls, ATE, data acquisition, and  
precision controls as well as professional quality audio.  
The AD8671/AD8672/AD8674 are specified over the extended  
industrial temperature range (–40°C to +125°C).  
The AD8671/AD8672 are available in the 8-lead SOIC and  
8-lead MSOP packages. The AD8674 is available in 14-lead  
SOIC and 14-lead TSSOP packages.  
Surface-mount devices in MSOP packages are available in tape  
and reel only.
