ST TSU104IQ4T

CMOS满摆幅9 kHz

Overview

STMicroelectronics’ TSU nanopower op amps, which are part of the ST micropower op-amp family, provide 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 TSU104IQ4T are single, dual and quad configurations, respectively. Drawing less current per op amp than the typical self-discharge current of a lithium-ion battery, TSU devices enable longer operation from small coin cells in applications such as energy-harvesting systems, personal medical monitors, smoke alarms, passive infrared detectors, wireless sensors, security cameras, and smart tags. Specified maximum current over the temperature range is as low as 800 nA at 1.8 V or 850 nA at 3.3 V and typical current consumption is just 580 nA at 25°C and 1.8 V. The maximum input offset voltage is 4.5 mV and input bias current is 300 pA, also specified over the full temperature range. The devices have rail-to-rail inputs and outputs, operate from 1.5 V to 5.5 V, and have typical gain-bandwidth product of 8 kHz.
