TLE5309D

Dual GMR/AMR Angle Sensor

Specification

The sensor outputs 4 single-ended signals SIN_N, SIN_P, COS_N, and COS_P, which are centered at the

voltages for X or Y are defined in Equation (5).

(5)

The maximum amplitudes for the differential signals are centered at 0 V and defined for X or Y as given in

Equation (6):

(6)

Differential offset is of X or Y is defined in Equation (7).
