The LTC2645 quad-channel, 12-bit/10-bit/8-bit PWM-to-voltage output digital-to-analog converters (DACs) with 10-ppm/°C references convert PWM input signals to 12-bit accurate, stable, buffered voltage outputs in less than 8 µs, eliminating the ripple and delay typically associated with analog filters. The devices provide a bolt-on solution to accurately set and adjust four voltages without a single line of code required. Available in 16-lead MSOPs, a dual version, the LTC2644, is available in a 12-lead MSOP package. For more info and datasheets, go to http://www.linear.com/product/LTC2645
