LMV321, LMV358, LMV324
Single, Dual, Quad
Low-Voltage, Rail-to-Rail
Operational Amplifiers
The LMV321, LMV358, and LMV324 are CMOS single, dual, and
quad low voltage operational amplifiers with rail−to−rail output
swing. These amplifiers are a cost−effective solution for applications
where low power consumption and space saving packages are critical.
Specification tables are provided for operation from power supply
voltages at 2.7 V and 5 V. Rail−to−Rail operation provides improved
signal−to−noise preformance. Ultra low quiescent current makes this
series of amplifiers ideal for portable, battery operated equipment. The
common mode input range includes ground making the device useful
for low−side current−shunt measurements. The ultra small packages
allow for placement on the PCB in close proximity to the signal source
thereby reducing noise pickup.
Features
• Operation from 2.7 V to 5.0 V Single−Sided Power Supply
• LMV321 Single Available in Ultra Small 5 Pin SC70 Package
• No Output Crossover Distortion
• Industrial temperature Range: −40°C to +85°C
• Rail−to−Rail Output
• Low Quiescent Current: LMV358 Dual − 220 mA, Max per Channel
• No Output Phase−Reversal from Overdriven Input
• These are Pb−Free Devices
Typical Applications
• Notebook Computers and PDA’s
• Portable Battery−Operated Instruments
• Active Filters
