Specification

Figure 12

Period jitter definition is valid for measurement on rising-to-rising or falling-to-falling edge

Magnetic Input Characteristics

All magnetic input values specified at constant sinusoidal amplitude and constant offset over operating range,

unless otherwise specified. Magnetic values are referred to the location at the silicon surface. Typical values are

related to VDD = 12V and TA = 25°C.

Internal offset drift

1) Refer to Figure 6 “Offset calibration of TLE5041plusC” on Page 11. dB

Limit_X is a 99% criteria, calculated out of

measured sensitivity.

2)Threshold limit dBLimit_X is increased by 25% under influence of an in-plane magnetic induction perpendicular to

the sensitive direction (refer to Chapter 3.3 “Operating Range” on Page 15 of B

ext_XYZ).

Note: In typical encoder wheel applications, at large air gaps where dB

X is as low as dBLimit_X, the in-plane

magnetic induction perpendicular to the sensitive direction BY is smaller than 0.15mT.

3) Not subject to production test, verified by design/characterisation

4) dB

Startup_X is the minimum DNC at start-up.
