LMV301,pdf datasheet (Low Inpu

The LMV301 CMOS operational amplifier is ideal for single
supply, low voltage operation with a guaranteed 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 600W 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.
