Overview
The LPV358MM is a dual-channel, general-purpose, low-voltage, low-power operational amplifier produced by Texas Instruments (originally National Semiconductor). It is part of the LPV3xx-N family, which includes single (LPV321-N), dual (LPV358-N), and quad (LPV324-N) channel versions. These op-amps are designed for applications requiring low power consumption, low voltage operation, and space efficiency.
The LPV358MM is built using Texas Instruments's advanced submicron silicon-gate BiCMOS process, featuring bipolar input and output stages for improved noise performance and higher output current drive. This device is particularly suited for general-purpose low-voltage applications and portable devices due to its micropower supply current and rail-to-rail output swing capability.
