ONSEMI LMV931

LMV931, LMV932
Single and Dual Low
Voltage, Rail-to-Rail Input
and Output, Operational
Amplifiers
The LMV931 Single and LMV932 Dual are CMOS low−voltage
operational amplifiers which can operate on single−sided power
supplies (1.8 V to 5.0 V) with rail−to−rail input and output swing.
Both devices come in small state−of−the−art packages and require
very low quiescent current making them ideal for battery−operated,
portable applications such as notebook computers and hand−held
instruments. Rail−to−Rail operation provides improved
signal−to−noise performance plus the small packages allow for closer
placement to signal sources thereby reducing noise pickup.
The single LMV931 is offered in space saving SC70−5 package.
The dual LMV932 is in a Micro8. These small packages are very
beneficial for crowded PCB’s.
Features
• Performance Specified on Single−Sided Power Supply: 1.8 V, 2.7 V, and

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may
affect device reliability.
ESD data available upon request.
1. Continuous short−circuit operation to ground at elevated ambient temperature can result in exceeding the maximum allowed junction
temperature of 150°C. Output currents in excess of 45 mA over long term may adversely affect reliability. Shorting output to either V+
or V− will adversely affect reliability.
