Analog/PWM Output Linear IC Designed For Output Redundancy

Dual analog/PWM output, programmable linear IC allows the user to optimize the device in a finished sensor assembly.

The A1359 dual analog/PWM output, one-time programmable, linear IC from Allegro allows the user to optimize the device in a finished sensor assembly. The IC provides a dual tracking output, where the PWM output tracks the analog output to within a +/-3% mismatch. require. The new programmable linear device has been designed specifically to achieve high accuracy in conjunction with redundant outputs in displacement and angular position applications, and is targeted at the automotive market with end applications including electronic power steering (torque sensing), transmission component position, brake and clutch cylinder position and various other industrial applications. The accuracy of the device is enhanced via programmability on the analog output pin for end-of-line optimization. OTP, using non-volatile memory, optimizes device sensitivity and the QVO and Duty Cycle for a given application or circuit. It also allows for optimized performance over temperature through programming the temperature coefficient for both sensitivity and QVO/DC at the end of line test. The A1359LLETR-T linear IC is available in a TSSOP-08 (suffix LE) SMT package and is priced at $1.45 each/1,000.
