A1315: Linear Hall-Effect Sensor ICs with Analog Output

The Allegro A1315 linear Hall-effect sensor ICs has been designed specifically to meet higher accuracy and smaller package requirements. 

The accuracy of this device is enhanced via end-of-line optimization and features non-volatile memory to optimize device sensitivity and the quiescent voltage output for a given application or circuit.

The A1315 is an ideal solution for use in automotive and industrial applications requiring high accuracy, and operate across an extended temperature range, –40°C to 150°C.

The A1315 is offered in two package styles. The LH is a SOT-23W style, miniature, low profile package for surface-mount applications. The UA is a 3-pin, ultra-mini, single inline package (SIP) for through-hole mounting. Both packages are lead (Pb) free, with 100% matte tin leadframe plating.

• 3.3 V supply operation
• QVO temperature coefficient programmed at Allegro™ for improved accuracy
• High bandwidth, low noise analog output
• High speed chopping scheme minimizes QVO drift across operating temperature range
• Temperature-stable quiescent voltage output and sensitivity
