A1309
Overview
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.
- 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)
