FEATURES Nanopower Op Amp, Comparator, and 0.58V Reference in Single 4 mm 2 Package Ultra Low Total Supply Current: 1.6µA (max) Supply Voltage Operation: 0.8V to 2.5V Internal 0.58V Reference Op Amp and Comparator Input Ranges are Rail-to-Rail Unity-gain Stable Op Amp with A VOL = 104dB Op Amp Output: Rail-to-Rail and Phase- Reversal-Free Internal ±7.5mV Comparator Hysteresis 20µs Comparator Propagation Delay Resettable Latched Comparator TS12011: Push-pull Rail-to-Rail Output Stage with Crowbar-Current Free Switching TS12012: Open-drain Output Stage for Wired- OR or Mixed-Voltage System Applications APPLICATIONS Low-Frequency, Local-Area Alarms/Detectors Smoke Detectors and Safety Sensors Infrared Receivers for Remote Controls Instruments, Terminals, and Bar-Code Readers Battery-powered Systems Smart-Card Readers DESCRIPTION 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.
