LMV654

Quad, 12 MHz, Low Voltage, Low Power Amplifier

General Description

National’s LMV654 is a high performance, low power quad

operational amplifier IC implemented with National’s ad-

vanced VIP50 process. The LMV654 features 12 MHz of

bandwidth while consuming only 119 µA 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

Ω 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 (−40˚C to +125˚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
