Outputs of KMA200

The output of the KMA200 is either digital or analog, depending on the control word stored

in the EEPROM. The analog output consists of a standard and a programmable output

stage. The programmable output stage allows four different characteristics; mode 1,

mode 2, mode 3 or none output. The digital output has two different modes; mode 5 and

mode 6.

Analog output

In the analog output mode the measured angle value is converted linear into a value that

stage to pin DATA/OUT1. The same value is fed to a second output stage that is

connected to pin CLK/OUT2. This second output stage is programmable to one of four

different output characteristics; mode 1, mode 2, mode 3 or high-impedance state output.

(see Figure 3).

For mode 1 the valid output voltage range at pin CLK/OUT2 is identical to the output

voltage range of the standard analog voltage but the output characteristic is inverted

(see Figure 4).

from the angle value (see Figure 6).

When the KMA200 detects an error condition, it switches the analog outputs into

high-impedance state. The outputs are forced to lie in the upper or lower diagnostic range

by the external pull-up or pull-down resistors.
