A1389
Overview
New applications for linear output Hall-effect sensors-such as displacement and angular position-require higher accuracy and smaller package sizes. The Allegro A1388 and A1389 linear Hall-effect sensor ICs have been designed specifically to meet both requirements.
- 5.0 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
