
DESCRIPTION
The UTC LMV331 is the single version, which is available in
space saving SOT23-5 packages. The UTC LMV331 is the most
cost-effective solution where space, low voltage, low power and
price are the primary specification in circuit design for portable
consumer products. The UTC LMV331 have bipolar input and
output stages for improved noise performance.

FEATURES
* Low operating voltage 2.7-5V.
* Industrial temperature range (−40˚C~+85˚C)
* Low supply current 60µA
* Input common mode voltage range includes ground
* Low output saturation voltage 0.2V

Notes: 1. The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power
dissipation at any ambient temperature is PD=(TJ(max)-TA)/θJA. All numbers apply for packages soldered
directly into a PC board.
2. Typical Values represent the most likely parametric norm.
3. All limits are guaranteed by testing or statistical analysis.
