PWM DAC vs. StandalonePWM DAC vs. Standalone

In today’s highly competitive electronics environment, designers are constantly looking for ways to reduce overall system costs. One of the most commonly asked questions that analog specialists at digital microcontroller (MCU) companies hear from customers is, is the almost cost-free Pulse-Width-Modulation (PWM) Digital-to-Analog Converter (DAC) good enough for my application, or do I need a higher-performance, standalone DAC instead?”.......
