DESCRIPTION
TI’s LMV651/LMV652/LMV654 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 op amp class. The
LMV651/LMV652/LMV654 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 op amps 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
LMV651/LMV652/LMV654 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 2.7V and 5.5V. These op amps 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.
