Frequently Asked Questions
What precision reference does LTC2645CMS-L12#PBF include, and how does it affect output accuracy?
The LTC2645CMS-L12#PBF integrates a 10 ppm/°C internal voltage reference, which provides stable output accuracy over the full -40°C to 85°C operating range. This eliminates the need for an external reference component, reducing BOM cost and PCB area while maintaining 12-bit resolution across all 4 DAC channels.
How does the PWM-to-voltage conversion work in LTC2645CMS-L12#PBF, and what PWM frequency ranges are supported?
The LTC2645CMS-L12#PBF accepts PWM signals and converts the duty cycle directly to a proportional DC voltage output at each of its 4 channels with 12-bit resolution. The device filters the PWM input internally, enabling microcontrollers with standard PWM peripherals to generate precise analog control voltages without external RC filters.
For which compact industrial control or calibration designs is the MSOP-12 package of LTC2645CMS-L12#PBF a good fit?
The MSOP-12 package of LTC2645CMS-L12#PBF suits compact industrial control boards needing 4 independent analog setpoints, such as programmable power supplies, multi-axis motor drives, or calibration instruments. With a 2.7V to 5.5V supply range and rail-to-rail outputs, it integrates easily into both 3.3V and 5V system designs with minimal PCB area.
When is LTC2645CMS-L12#PBF preferred over a SPI or I2C DAC for analog control?
LTC2645CMS-L12#PBF is preferred when the host MCU already generates PWM signals and no spare SPI or I2C bus is available. By accepting PWM inputs directly and delivering 12-bit accuracy with the integrated 10 ppm/°C reference, it simplifies firmware and hardware design compared to digital-bus DACs in embedded control applications.
