Touchstone's TS12011 and the TS12012 combine a 0.6 V reference, a 20 µs analog comparator, and a unity-gain stable operational amplifier in a single package. Both devices operate from a single 0.8 V to 2.5 V power supply, and consume less than 1.5 µA total supply current. Optimized for ultra-long life, single-cell and battery-powered applications, these devices expand Touchstone’s growing “NanoWatt Analog™“ high-performance analog integrated circuits portfolio.

Both the analog comparator and the op amp feature rail-to-rail input stages. The analog comparator exhibits ±7.5 mV of internal hysteresis for clean, chatter-free output switching. The TS12011 output stage is push-pull, where as the TS12012’s output stage is open-drain for mixed-voltage system applications. The internal reference to sinks or sources up to 0.1 µA load currents. When compared against similar products, the TS12011 and the TS12012 offer a factor-of-20 lower power consumption, and at least a 55% reduction in PCB area.

The TS12011 and the TS12012 are fully specified over the -40°C to 85°C temperature range, and each is available in a low profile, 10-pin 2 x 2 mm TDFN package with an exposed back-side paddle.
