LMV301 Low Input Bias Current, 1.8V Op Amp w/ Rail-to-Rail Output

FEATURES  
DESCRIPTION  
The LMV301 CMOS operational amplifier is ideal for  
single supply, low voltage operation with an ensured  
operating voltage range from 1.8V to 5V. The low  
input bias current of less than 0.182pA typical,  
eliminates input voltage errors that may originate from  
small input signals. This makes the LMV301 ideal for  
electrometer applications requiring low input leakage  
such as sensitive photodetection transimpedance  
amplifiers and sensor amplifiers. The LMV301 also  
features a rail-to-rail output voltage swing in addition  
to a input common-mode range that includes ground.  
The LMV301 will drive a 600Ω resistive load and up  
to 1000pF capacitive load in unity gain follower  
applications. The low supply voltage also makes the  
LMV301 well suited for portable two-cell battery  
systems and single cell Li-Ion systems.

The LMV301 exhibits excellent speed-power ratio,  
achieving 1MHz at unity gain with low supply current.  
The high DC gain of 100dB makes it ideal for other  
low frequency applications.  
Sample and Hold Circuits  
Low Frequency Active Filters  
The LMV301 is offered in a space saving SC70  
package, which is only 2.0X2.1X1.0mm. It is also  
similar to the LMV321 except the LMV301 has a  
CMOS input.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
