MikroElektronika MIKROE-6137, 10 Bit Smart DAC For General Purpose Input To PWM Conversion From Texas Instruments

The MikroElektronika Automotive is an application-specific, lookup table (LUT) based GPI-to-PWM converter. This device has a 10-bit GPI-to-voltage output converter and a voltage-to-PWM converter. Both these circuits can be externally connected to create a GPI-to-PWM converter. Three GPIs are mapped to eight 10-bit digital codes that represent the voltage output. There is a programmable delay at the GPIs for eliminating glitches on these inputs.
