Integrated Circuits use 1.5 µA Icc max.

Press Release Summary:

Operating down to 0.65 V, Models TS12011 and TS12012 combine 0.6 V reference, 20 µs analog comparator, and unity-gain stable op amp in 4 mm² package. Model TS12011 has push-pull output, while Model TS12012 has open-drain output. Both analog comparator and op amp feature rail-to-rail input stages, and analog comparator has ±7.5 µs of internal hysteresis for chatter-free output switching. Applications include local-area alarms/detectors, safety sensors, and IR receivers for remote controls.

Original Press Release:

Touchstone Semiconductor's New All-in-One Op Amp, Comparator and Reference ICs Cut Power by More Than 10X

New TS12011 and TS12002 Use Only 1.5 µA Icc Max

MILPITAS, Calif. - Touchstone Semiconductor, a developer of high-performance, low power analog integrated circuit (IC) solutions, today announced the new TS12011 and TS12012, 1.2µW (microwatt) operational amplifier (op amp), comparator and voltage reference in one IC.

This 10 times reduction in power consumption and operation down to 0.65V (volts) enables always-on, single-cell operation that was not previously possible.

Both the TS12011 and TS12012 combine a 0.6V reference, 20µs (microsecond) analog comparator and unity-gain stable operational amplifier in a single package. The TS12011 has a push-pull output, and the TS12012 has an open-drain output.

Both the analog comparator and the op amp feature rail-to-rail input stages. 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.

The TS12011 and TS12012 are ideal for 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; and smart-card readers.
