LMV821M7

Instrumentation, Op Amps, Buffer Amps Overview

The LMV821M7 is a single-channel operational amplifier from the LMV82x series, manufactured by Texas Instruments (originally National Semiconductor). It features low power consumption of 400 μA max at 5 V and a gain bandwidth product of 5.5 MHz. The device operates on a supply voltage range of 2.5 V to 5.5 V with rail-to-rail output swing. Key electrical parameters include an input offset voltage of 0.8 mV max at 25°C and an input bias current of 100 nA. It supports an extended operating temperature range from -40°C to +125°C and offers high ESD tolerance suitable for automotive applications.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation carefully, as the LMV821 part number is produced by multiple vendors including Texas Instruments, STMicroelectronics, and ON Semiconductor. Confirm that the specific suffix matches the required package type and performance specifications. Ensure compatibility with your system's voltage and temperature requirements before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op-amp with rail-to-rail output is required in a compact SC-70-5 package. It is suitable for designs needing low power consumption and moderate bandwidth. Consider alternative variants like LMV820 if a shutdown feature is needed, or LMV822/LMV824 for dual/quad configurations.

Instrumentation, Op Amps, Buffer Amps Part Context

The LMV821 belongs to the LMV82x family of low voltage, low power operational amplifiers. This series includes single (LMV821), dual (LMV822), and quad (LMV824) versions. The family is designed to outperform industry standards like the LMV321, particularly in gain bandwidth product. Variants such as LMV820, LMV823, and LMV825 add a power-saving shutdown mode.
