AX31002
Bipolar Tone Ringer IC
Page No. : 1/5
AX31002 Series
Description
The AX31002 is a bipolar integrated circuit. It is designed for telephone bell
replacement. It can also be used as alarms or other alerting devices.
Features
• Current consumption is small
• Oscillation frequency is variable
• Adjustable start-up current
• Higher driving capability
• Built-in threshold circuits prevent false triggering due to power noise as well as 'chirps' due to rotary dial
• Few external components
• Easy connection to telephone system
Applications
• Telecom Tone Ringer Set
