The accuracy of the IC is enhanced via programmability on the analogue output pin for end-of-line optimisation without the added complexity and cost of a fully programmable device.
The A1359 features one-time programming using non-volatile memory to optimise device sensitivity and to set the quiescent output voltage and duty cycle for a given application or circuit. The sensitivity range of the A1359 is 4 mV/G to 9 mV/G, and the quiescent analogue output is adjustable around 50% of the supply rail voltage.
Optimised performance at different temperatures is achieved by programming the temperature coefficient for sensitivity, quiescent output voltage and duty cycle at end-of-line test.
The A1359 is targeted at the automotive and industrial markets, with end applications including torque sensing in electronic power steering and position sensing of transmission components, brakes and clutch cylinders.
The A1359LLETR-T is available in a TSSOP-08 (suffix LE) surface-mount package.
