Touchstone Semiconductor announced the new TS12011 and TS12012, 0.9µW operational amplifier (op amp), comparator and voltage reference in one IC.
This 10 times reduction in power consumption and operation down to 0.8V enables always-on, single-cell operation that was not previously possible.
Both the TS12011 and TS12012 combine a 0.6V reference, 20µs 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.
Both the analog comparator and the op amp feature rail-to-rail input stages. The analog comparator has ±7.5mV of internal hysteresis for clean, chatter-free output switching. The internal reference is designed to sink or source up to 0.1µA load currents.
The TS12011 and TS12012 are ideal for low-frequency, battery-powered systems including local-area alarms/detectors; smoke detectors and safety sensors, infrared receivers for remote controls; instruments, terminals, and bar-code readers; and smart-card readers.
