ST brings Nanopower Op-Amps to boost System power intake

STMicroelectronics has introduced new TSU10X nanopower Op-Amps, to its micro power Op-Amp family, providing ultra-low power consumption over the full operating temperature range, allowing engineers to optimize power budget and battery lifetime wherever quiescent current is the major concern. The TSU101, TSU102 and TSU104 are single, dual and quad configurations, respectively.

Specified maximum current over the temperature range is as low as 800nA at 1.8V or 850nA at 3.3V and typical current consumption is just 580nA at 25°C and 1.8V. The maximum input offset voltage is 4.5mV and input bias current is 300pA, also specified over the full temperature range. The devices have rail-to-rail inputs and outputs, operate from 1.5V to 5.5V, and have typical gain-bandwidth product of 8 kHz.

Joining ST’s TS88x series of nanopower comparators, the TSU10x devices are available immediately, in SC70, SOT23-5, DFN8 2x2, MiniSO8, QFN16 3x3 or TSSOP14 packages depending on configuration. Prices start from $0.50 for 1,000 units.
