Key Features
- Dual 10-bit buffered voltage output DACs with separate reference inputs for each DAC, which can be configured as buffered or unbuffered inputs.
- Operates from a single 2.5 V to 5.5 V supply with low power consumption: 230 μA at 3 V and 1.5 mW at 5 V.
- On-chip output amplifiers provide rail-to-rail output swing with a slew rate of 0.7 V/μs.
- Versatile 3-wire serial interface compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards, operating at clock rates up to 30 MHz.
- Power-on reset circuit ensures DAC outputs power up to 0 V and remain there until a valid write to the device takes place.
- Asynchronous active low CLR pin clears both DACs to 0 V.
- Simultaneous update of DAC outputs via the asynchronous LDAC input.
- Power-down feature reduces current consumption to 200 nA at 5 V (50 nA at 3 V) with software-selectable output loads.
- SDO pin allows for daisy-chaining applications.
Applications
- Portable battery-powered instruments.
- Digital gain and offset adjustment.
- Programmable voltage and current sources.
- Programmable attenuators.
- Automotive applications.
