LMV654
Quad, 12 MHz, Low Voltage, Low Power Amplifier
General Description
National鈥檚 LMV654 is a high performance, low power quad
operational amplifier IC implemented with National鈥檚 ad-
vanced VIP50 process. The LMV654 features 12 MHz of
bandwidth while consuming only 119 碌A(chǔ) of current per am-
plifier, which is an exceptional bandwidth to power ratio in
this op amp class. The LMV654 is unity gain stable and
provides an excellent solution for general purpose amplifica-
tion in low voltage, low power applications.
The LMV654 provides superior performance and economy in
terms of power and space usage. The LMV654 has a maxi-
mum input offset voltage of 1.8 mV, a rail-to-rail output stage
and an input common-mode voltage range that includes
ground. The LMV654 provides a PSRR of 95 dB, a CMRR of
100 dB and a total harmonic distortion (THD) of 0.003% at
1 kHz frequency and 600鈩?load
The LMV654 has an operating supply voltage range from
2.7V to 5.5V. The LMV654 can operate over a wide tempera-
ture range (鈭?0藲C to +125藲C) making the op amp ideal for
automotive applications, sensor applications and portable
equipment applications. The LMV654 is offered in the 14-pin
TSSOP package
