TS393中文资料微功耗CMOS双路电压比较器数据手册ST规格书

描述 Description

The TS393 device is a micropower CMOS dual voltage comparator with extremely low consumption of 9 μA typically per comparator (20 times less than the dual bipolar LM393 device). Similar performance is offered by the dual micropower comparator TS3702 with a push-pull CMOS output.

Thus response times remain similar to the LM393 device.

特性 Features

• Extremely low supply current: typically 9 μA per comparator
• Wide single supply range 2.7 V to 16 V or dual supplies (±1.35 V to ±8 V)
• Extremely low input bias current: 1 pA typical
• Extremely low input offset current: 1 pA typical
• Input common-mode voltage range includes ground
• High input impedance: 1012 Ω typ.
• Fast response time: 2.5 μs typ. for 5 mV overdrive
• Pin-to-pin and functionally compatible with dual bipolar LM393

简介

TS393属于集成电路（IC）的比较器。由ST制造生产的TS393比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。
