1.5µ0.8V纳功率运放比较器和参考TS12011/TS12012

　　DESCRIPTION The TS12011/TS12012 combine a 0.58V reference， a 20µs comparator， and a unity-gain stable op amp in a single IC. All three devices operate from a single 0.8V to 2.5V power supply and consume less than 1.6µA total supply current. Supply current for all three functions over 0.8V to 2.5V supply range is guaranteed 1.6µA max. Super-flexible for crafting voltage detectors， timers， and wake-up circuits， these bundled functions exhibit low shoot-through currents and graceful power-down modes. Both the comparator and the op amp feature rail-to-rail input stages. The latching comparator exhibits ±7.5mV of internal hysteresis for clean， chatter-free output switching. When compared against similar products， the TS12011/TS12012 offer a factor-of-20 lower power consumption and at least a 55% reduction in pcb area. The TS12011’s comparator has a push-pull output stage with break-before-make switches for low shootthrough currents. The TS12012’s comparator has an open-drain output having no parasitic diode to VDD， for interfacing to wired-OR or mixed-voltage logic. 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.
