Key Features
- On-Chip Reference: 1.25 V or 2.5 V with 5 ppm/°C temperature coefficient, enabling a full-scale output range of 2.5 V or 5 V respectively.
- Power-On Reset: Ensures DAC output powers up to 0 V or midscale and remains at this level until a valid write takes place.
- Power-Down Capability: Reduces current consumption to 400 nA at 5 V, with software-selectable output loads while in power-down mode.
- Simultaneous Update: Outputs of all DACs can be updated simultaneously using the LDAC function, with user-selectable DAC channels.
- Asynchronous CLR: Updates all DACs to a user-programmable code—zero scale, midscale, or full scale.
- Serial Interface: Versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, operating at clock rates up to 50 MHz.
- Output Amplifier: On-chip precision output amplifier enabling rail-to-rail output swing.
