1.2µW Op amp, comparator and reference IC in a single chip from Touchstone

Touchstone Semiconductor has announced the 1.2µW (microwatt) operational amplifier (op amp), comparator and voltage reference in one IC, the new TS12011 and TS12012.
The analog comparator has ±7.5µs of internal hysteresis for clean, chatter-free output switching. The internal reference is designed to sink or source up to 0.1µA (microamp) load currents.

Applications:
1. Low-frequency, local-area alarms/detectors
2. Smoke detectors and safety sensors, infrared receivers for remote controls
3. Instruments, terminals, and bar-code readers
4. Battery-powered systems
5. Smart-card readers

Specifications:
1. Nanopower Op Amp, comparator, and 0.6V reference in single 4 mm2 package
2. Total supply current: 1.5µA (max)
3. Supply voltage operation: 0.8V to 2.5V
4. Internal 0.6V reference
5. Input range for Op Amp and comparator: Rail-to-Rail
6. Unity-gain stable Op Amp with AVCL = 110dB (decibel)
7. Op Amp output: Rail-to-Rail and phase-reversal-free
8. Internal ±7.5mV comparator hysteresis
9. 20µs comparator propagation delay
10. Resettable latched comparator
11. Operating temperature range: -40°C to +85°C
12. TS12011: Push-pull Rail-to-Rail output Stage with crowbar-current free switching
13. TS12012: Open-drain output stage for wired-OR or mixed-voltage system applications
14. Low-profile, 10-pin 2x2 mm TDFN (Thin Dual Flat No Leads) package

These devices are in stock and ready to ship at a price of $1.70 each in 1,000 piece quantities. The products are in stock and available from the distributor Future Electronics.
