Dual-mode op amp for critical sensor applications.(Integrated Circuits)

ECN-Electronic Component News, December, 2004

National Semiconductor has launched what is said to be the lowest supply current, dual power mode operational amplifier available. The LMV422 has a power-saving mode that allows customers to reduce power consumption while maintaining an active circuit. This allows for faster turn-on times in smoke detectors and other sensor interface applications where reaction time is critical. This dual, rail-to-rail op amp has an external control pin, and it can be switched between a very low-power (2 [micro]A per channel) and low- bandwidth (27 kHz) mode to a full-power (400 [micro]A per channel) wide-bandwidth (8 MHz) mode. These combinations reduce power consumption, maintain necessary charges on the coupling capacitors and shorten the time needed to stabilize the signal after...
