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

Touchstone Semiconductor, a developer of high-performance, low power analog integrated circuit solutions, announced the new TS12011 and TS12012, 0.9µW operational amplifier (op amp), comparator and voltage reference in one IC.

This 10 times reduction in power consumption and operation down to 0.8V enables always-on, single-cell operation that was not previously possible.

The TS12011 and the TS12012 are fully specified over the -40°C to +85°C temperature range. Each is available in a low-profile, 10-pin 2x2mm TDFN package.

Both the analog comparator and the op amp feature rail-to-rail input stages. The analog comparator has +/-7.5mV of internal hysteresis for clean, chatter-free output switching. The internal reference is designed to sink or source up to 0.1µA load currents.

The TS12011 and TS12012 are well suited for low-frequency, battery-powered systems including local-area alarms/detectors; smoke detectors and safety sensors, infrared receivers for remote controls; instruments, terminals, and bar-code readers; and smart-card readers.

 The TS12011 and the TS12012 are fully specified over the -40 to +85°C temperature range. Each is available in a low-profile, 10-pin 2 x 2mm TDFN package.

The TS12011 and TS12012 are in stock and ready to ship. Pricing starts at $1.70 each in 1,000 piece quantities.
