LM38510/11202中文资料Low Power Low Offset Voltage Dual Comparators数据手册TI规格书

描述 Description

General Description
The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
