LMV301 Datasheet | National Semiconductor

Description 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 0.182p A 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 mon-mode range that includes ground. The LMV301 will drive a 600Ω resistive load and up to 1000p F 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 100d B makes it ideal for other low frequency applications. The LMV301 is offered in a space saving SC-70 package, which is only 2.0X2.1X1.0mm. It is also similar to the LMV321 except the LMV301 has a CMOS input.
