LMV981, LMV982
Single and Dual Low
Voltage, Rail-to-Rail Input
and Output, Operational
Amplifiers with Shutdown
The LMV981 Single and LMV982 Dual are 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 allows for optimal
signal−to−noise applications plus the small packages allow for closer
placement to signal sources further enhancing overall signal chain
performance.
The LMV981 Single and LMV982 Dual both have a shutdown pin
that can be used to disable the device and further reduce power
consumption. Shutdown is implemented by driving the SHDN Pin LOW.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device
functionality should not be assumed, damage may occur and reliability may be affected.
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.
