DESCRIPTION  
Rail-to-Rail Output:  
The OPA2180 and OPA4180 operational amplifiers  
use zero-drift techniques to simultaneously provide  
low offset voltage (75 μV), and near zero-drift over  
Input Includes Negative Rail  
Low Bias Current: 250 pA (typ)

and  
temperature.  
These  
miniature,  
high-precision, low quiescent current amplifiers offer  
high input impedance and rail-to-rail output swing  
within 18 mV of the rails. The input common-mode  
range includes the negative rail. Either single or dual  
supplies can be used in the range of +4.0 V to +36 V  
(±2 V to ±18 V).  
MicroSIZE Packages  
The dual version is offered in MSOP-8 and SO-8  
packages. The quad is offered in SO-14 and  
TSSOP-14 packages. All versions are specified for  
operation from 40°C to +105°C.
