TS3704中文资料微功耗四路CMOS电压比较器数据手册ST规格书

描述 Description

The TS3704 is a micropower CMOS quad voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM339). The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual open-collector output comparators.

Thus response times remain similar to the LM339.

特性 Features

• High input impedance: 1012Ωtyp
• Input common-mode voltage range includes GND
• Pin-to-pin and functionally compatible with bipolar LM339
• Push-pull cmos output (no external pull-up resistor required)
• Wide single supply range 2.7V to 16V or dual supplies (±1.35V to ±8V)
• Extremely low supply current: 9µa typ/comp.
• Extremely low input offset current: 1pA typ.
• Last response time: 2µs typ. for 5mV overdrive
• Extremely low input bias current: 1pA typ.

简介

TS3704属于集成电路（IC）的比较器。由制造生产的TS3704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。
