TS12012: A 0.8V/1.5µA Nanopower Reference/Op Amp/Comparator in TDFN22EP-10

The TS12011/TS12012 combine a 0.58V reference, a 20μs analog comparator, and a unity-gain stable operational amplifier in a single package. All three devices operate from a single 0.8V to 2.5V power supply and consume less than 1.6μA 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 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.
