DESCRIPTION  
The OPA211 series of precision operational amplifiers achieves very low 1.1nV/Hz noise density with a supply  
current of only 3.6mA. This series also offers rail-to-rail output swing, which maximizes dynamic range.  
The extremely low voltage and low current noise, high speed, and wide output swing of the OPA211 series make  
these devices an excellent choice as a loop filter amplifier in PLL applications.  
In precision data acquisition applications, the OPA211 series of op amps provides 700ns settling time to 16-bit  
accuracy throughout 10V output swings. This ac performance, combined with only 125μV of offset and  
0.35μV/°C of drift over temperature, makes the OPA211 ideal for driving high-precision 16-bit analog-to-digital  
converters (ADCs) or buffering the output of high-resolution digital-to-analog converters (DACs).
