GMW Sin/Cos to Analog Interpolator IC, GMW360A
 |
| |
The GMW360A Interpolator IC is designed to be compatible with the Sentron 2SA-10, 2-Axis angular sensing IC,
however it will work with any SIN and COS signal input with the required input amplitude. The GMW360A is based
on the Cypress PSoCTM, CY8C24123A, Mixed-Signal Array device. The GMW360A converts orthogonal SIN and
COS signals to Analog and PWM output signals proportional to the angle with 9 bit resolution.
The PWM output can
be turned off by connecting the “PWM Disable” pin to “COM”. In addition to the absolute angle position outputs,
the GMW360A detects when the magnetic strength of the magnet is too low and provides a discrete magnet “Out of
Range” signal. The device incorporates an input voltage “Offset Null” capability which is activated by momentarily
connecting the PWM output pin to VDD and applying power.
The electrical Zero Angle position can be set to correlate
to any mechanical position within 360 degrees. This is accomplished by momentarily connecting the Analog output
pin to VDD and applying power. The IC only requires one external component (bypass capacitor) and operates with
a single 5 Volt supply
The GMW360A is RoHS compliant.
