[a]

% FS = percent of full scale = accuracy in % per period, where 100% is the angle range of one electrical period.

For rotary multi-period designs, one electrical period = 360° (one full turn) divided by the number of periods per turn.

Examples:



A 3-periodic coil design (3

 120°) has a typical mechanical accuracy of ±0.2% per 120° = ±0.24°



A 4-periodic coil design (4

 90°) has a typical mechanical accuracy of ±0.2% per 90° = ±0.18°

Ambient Temperature Range

The minimum ambient temperature for the IPS2200 is -40°C.

The maximum ambient temperature depends on the following factors:



The maximum junction temperature. See Table 5 for details.



The selected transmitter coil current. The total power consumption of the chip depends on the internal power

consumption and the user programmable current for the transmitter coil.



The minimum usable coil current in a given application. Note that smaller coil inductances require more

transmitter coil current, and larger coil inductances can operate with less coil current. The maximum allowed

transmitter coil current is shown in Table 5.



The Renesas internal part qualification. The IPS2200 is qualified for -40°C to +125°C ambient temperature.
