The TS12011 and the TS12012 combine a 0.6V reference, a 20µs analog comparator, and a unity-gain stable operational amplifier in a single package. Both devices operate from a single 0.8V to 2.5V power supply and consume less than 1.5µA 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 ±7.5mV 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 was designed to sink or source up to 0.1µA 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 2x2mm TDFN package with an exposed back-side paddle.
