Quad-channel digital-to-analog converter
The LTC2645 is a quad-channel 12-bit/10-bit/8-bit PWM-to-voltage output digital-to-analog converter convert PWM input signals to 12-bit accurate, stable, buffered voltage outputs in less than 8µs. The LTC2645 provides a bolt-on solution to set and adjust four voltages without a single line of code required. The LTC2645 is used for biasing, calibration, level setting, power supply adjustment, and to enable opto-isolated communications in applications such as industrial automation, 4-20 mA process control, instrumentation, test equipment and optical modules. Rail-to-rail DAC output is capable of sourcing or sinking 5 mA (3 V) or 10 mA (5 V), and offers a full-scale output of 2.5 V using the internal 10ppm/°C reference or a full-scale output equal to the external reference.The LTC2645 operates from a single 2.7 V-5.5 V supply, and supports PWM input voltages from 1.71 V-5.5 V.
