Ultra-low current consumption CMOS op-amp for battery-powered equipment

02-11-2020 | Toshiba | Power

Toshiba Electronics Europe GmbH offers a new CMOS operational amplifier providing ultra-low current consumption to its product line-up.

Operational amplifiers offer a multitude of uses, including boosting weak signals from sensors. To support extended use between charges of battery-operated equipment, covering IoT edge devices and other mobile devices including handheld POS terminals they must also provide lower current consumption.

The company has utilised its CMOS process technology to optimise the circuitry of the new TC75S102F op-amp, thereby reducing its power consumption to ultra-low levels. With a supply voltage between 1.5V and 5.5V, the new device is a full-range (rail-to-rail) input/output op-amp that provides higher performance than its predecessor. The supply current (IDD) will never exceed 0.6μA and is typically half that figure at just 0.27μA.

The new device is supplied in a SOT-25 package measuring only 2.9mm x 1.6mm x 1.1mm.
