What is LTC2645IMS-L12#PBF used for?
The LTC2645IMS-L12#PBF converts standard PWM signals from microcontroller GPIO pins directly into precision analog voltage outputs, eliminating the need for SPI or I2C DAC communication protocols in systems where only PWM peripherals are available. Its 4-channel architecture and integrated 10 ppm/°C reference make it suitable for multi-axis servo control, programmable power supply references, and industrial calibrator circuits requiring stable analog outputs across a -40 °C to 85 °C operating range. The device is commonly used in system-on-module designs, motor drive bias generation, and sensor excitation circuits where analog precision and minimal firmware overhead are priorities.

Frequently Asked Questions
How does the LTC2645IMS-L12#PBF convert a PWM signal into an analog voltage, and what resolution is achieved?
The LTC2645IMS-L12#PBF integrates a PWM pulse duration over a precise time window using an internal counter and converts the measured duty cycle into a 12-bit digital word, then outputs the corresponding analog voltage via an internal DAC. With 12-bit resolution, the device provides 4096 discrete output steps per channel, enabling voltage setting precision of approximately 0.024% of full scale per step.
What is the temperature coefficient of the internal reference in the LTC2645IMS-L12#PBF and why does it matter?
The integrated reference in the LTC2645IMS-L12#PBF has a 10 ppm/°C temperature coefficient, which means output voltage drift across temperature is minimal — roughly 0.1% over a 100 °C range. This low drift is critical in precision analog control and calibration systems where reference voltage shifts would translate directly into output errors, reducing the need for external precision references and associated BOM cost.
How many independent DAC output channels does the LTC2645IMS-L12#PBF provide, and can all channels be updated simultaneously?
The LTC2645IMS-L12#PBF provides 4 independent 12-bit DAC output channels, each accepting its own PWM input. When all 4 PWM inputs are synchronized or share the same period, the device updates all 4 output voltages simultaneously at the end of each PWM cycle, making it suitable for multi-axis actuator control and balanced differential signal generation where simultaneous output transitions are required.
