The 1.2 µW TS12011 and TS12012 all-in-one operational amplifier, comparator, and voltage reference is claimed to cut power by more than 10 times. This reduction in power consumption and operation down to 0.65 V enables always-on, single-cell operation that was not previously possible. The parts are ideal for low-frequency, local-area alarms/detectors; smoke detectors and safety sensors, infrared receivers for remote controls; instruments, terminals, and bar-code readers; battery-powered systems; and smart-card readers.
The ICs combine a 0.6 V reference, 20 µs analog comparator and unity-gain stable operational amplifier in a single package. The TS12011 has a push-pull output, and the TS12012 has an open-drain output.
In addition, both the analog comparator and the op amp feature rail-to-rail input stages. The analog comparator has ±7.5µs of internal hysteresis for clean, chatter-free output switching. The internal reference is designed to sink or source up to 0.1 µA load currents.(From $1.70 ea/1,000 available now)
