LMV301

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

Output

General 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 0.182pA 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 transimped-

ance 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 600

Ω 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.

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.
