3 Description
TI’s LMV65x devices are high-performance, low-
power operational amplifier ICs implemented with TI's
advanced VIP50 process. This family of parts
features 12 MHz of bandwidth while consuming only
116 μA of current, which is an exceptional bandwidth
to power ratio in this operational amplifier class. The
LMV65x devices are unity-gain stable and provide an
excellent solution for general-purpose amplification in
low-voltage, low-power applications.
This family of low-voltage, low-power amplifiers
provides superior performance and economy in terms
of power and space usage. These operational
amplifiers have a maximum input offset voltage of 1.5
mV, a rail-to-rail output stage, and an input common-
mode voltage range that includes ground. The
LMV65x provide a PSRR of 95 dB, a CMRR of 100
dB, and a total harmonic distortion (THD) of 0.003%
at 1-kHz frequency and 2-kΩ load.
The operating supply voltage range for this family of
parts is from 2.7 V and 5.5 V. These operational
amplifiers can operate over a wide temperature range
(−40°C to 125°C), making them ideal for automotive
applications, sensor applications, and portable
equipment applications. The LMV651 is offered in the
ultra-tiny 5-pin SC70 and 5-pin SOT-23 package. The
LMV652 is offered in an 8-pin VSSOP package. The
LMV654 is offered in a 14-pin TSSOP package.
