Product Details
●The AD5551 and AD5552 are single, 14-bit, serial input, voltage output DACs that operate from a single 2.7 V to 5.5 V. The The DAC output range extends from 0 V to VREF.
●These DACs provide 14-bit performance without any adjustments. The DAC output is unbuffered, which reduces power consumption and offset errors contributed by an output buffer.
●With an external op amp the AD5552 can be operated in bipolar mode generating a ±VREF output swing. The AD5552 also includes Kelvin sense connections for the reference and analog ground pins to reduce layout sensitivity. For higher precision applications, please refer to 16-bit DACs, AD5541, AD5542, and AD5544.
●The AD5551/AD5552 utilize a versatile 3-wire interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards. The AD5551 and AD5552 are available in 8-lead and 14-lead SOIC packages.
●Product Highlights
● 1. Single Supply Operation. The AD5551 and AD5552 are fully specified and guaranteed for a single 2.7 V to 5.5 V supply.
● 2. Low Power Consumption. Typically 0.625 mW with a 5 V supply.
● 3. 3-Wire Serial Interface.
● 4. Unbuffered output capable of driving 60 kΩ loads, which reduces power consumption as there is no internal buffer to drive.
● 5. Power-On Reset Circuitry.
● APPLICATIONS
● Digital gain and offset adjustment
