Overview
The LMV321-N, produced by Texas Instruments, is a single-channel, low-voltage operational amplifier designed for applications where space efficiency, low-voltage operation, and cost-effectiveness are crucial. This op-amp is part of the LMV321, LMV358, and LMV324 family, which are low-voltage versions of the traditional LM358 and LM324 op-amps. The LMV321-N operates within a voltage range of 2.7 V to 5.5 V, making it suitable for a wide range of low-voltage applications.
The device is available in compact packages such as the 5-Pin SOT-23 (DBV) and the even smaller 5-Pin SC70, which is approximately half the size of the SOT-23. This compact packaging enables the design of small portable electronic devices and allows for placement closer to the signal source to reduce noise and improve signal integrity.
