Description

The TS391 is an open collector, low−power voltage comparator

designed specifically to operate from a single supply over a wide range

of voltages. Operation from split power supplies is also possible.

This comparator also has a unique characteristic in that the input

common−mode voltage range includes ground, even though operated

from a single power supply voltage.

Features

• Wide Single Supply Voltage Range or Dual Supplies

• Low Supply Current (0.5 mA) Independent of Supply Voltage

(1 mW/Comparator at +5 V)

• Low Input Bias Current: 25 nA TYP

• Low Input Offset Current: ±5 nA TYP

• Low Input Offset Voltage: ±1 mV TYP

• Input Common Mode Voltage Range includes Ground

• Low Output Saturation Voltage: 250 mV TYP at IO = 4 mA

• Differential Input Voltage Range Equal to the Supply Voltage

• TTL, DTL, ECL, CMOS Compatible Devices

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant

• NCV Prefix for Automotive and Other Applications Requiring

Unique Site and Control Change Requirements; AEC−Q100

Qualified and PPAP Capable

NCV391属于集成电路（IC） > 比较器。安森美半导体公司制造生产的NCV391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。
