A1308 - Allegro

A1308 Linear Hall-Effect Sensor

New applications for linear output Hall-effect sensors, such as displacement and angular position, require higher accuracy and smaller package sizes. The Allegro A1308 and A1309 linear Hall-effect sensor ICs have been designed specifically to meet both requirements. These temperature-stable devices are available in both surface-mount and through-hole package.

Features

• 5 V supply operation
• QVO temperature coefficient programmed at Allegro™ for improved accuracy
• Miniature package options
• High-bandwidth, low-noise analog output
• High-speed chopping scheme minimizes QVO drift across operating temperature range
• Temperature-stable quiescent voltage output and sensitivity
• Precise recoverability after temperature cycling
• Output voltage clamps provide short-circuit diagnostic capabilities
• Undervoltage lockout (UVLO)
• Wide ambient temperature range:
  –40°C to 150°C (SOT-23W and SIP -L temp range),
  –40°C to 125°C (SIP -K temp range)
• Immune to mechan.
