These DACs contain nonvolatile memory (NVM), an internal reference, and a PMBus-compatible I2C interface. The DACx3401 operate with either an internal reference or with a power supply as the reference, and provide a full-scale output of 1.8 V to 5.5 V. The devices communicate through an I2C interface. These devices support I2C standard mode (100 kbps), fast mode (400 kbps), and fast+ mode (1 Mbps). These devices also support specific PMBus commands such as turn on/off, margin high/low, and more. The DACx3401 also include digital slew rate control, and support basic signal generation such as square, ramp, and sawtooth waveforms. The DACx3401 devices have a power-on-reset (POR) circuit that makes sure all the registers start with default or user-programmed settings using NVM. The DAC output powers on in high-impedance mode (default); this setting can be programmed to 10k Ω-GND using NVM. 8.2 Functional Block Diagram |
