AD5541CR

5 V ，串行输入电压输出， 16位DAC 5 V, Serial-Input Voltage-Output, 16-Bit DACs

Product Details

The AD5541/AD5542 are single, 16-bit, serial input, voltage output digital-to-analog converters DACs that operate from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREF.

The DAC output range extends from 0 V to VREF and is guaranteed monotonic, providing 1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of −40°C to +85°C. Offering unbuffered outputs, the AD5541/AD5542 achieve a 1 μs settling time with low power consumption and low offset errors. Providing a low noise performance of 11.8 nV/√Hz and low glitch, the AD5541/AD5542 is suitable for deployment across multiple end systems.

The AD5542 can be operated in bipolar mode, which generates a ±VREF output swing. The AD5542 also includes Kelvin sense connections for the reference and analog ground pins to reduce layout sensitivity.

The AD5541/AD5542 utilize a versatile 3-wire interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards. The AD5541/AD5542 are available in 8-lead and 14-lead SOIC packages.

**Product Highlights**

1. Single-Supply Operation. The AD5541 and AD5542 are fully specified and guaranteed for a single 2.7 V to 5.5 V supply.

2. Low Power Consumption. These parts consume typically 0.625 mW with a 5 V supply and 0.375 mW at 3 V.

3. 3-Wire Serial Interface.

4. Unbuffered Output Capable of Driving 60 kΩ Loads. This reduces power consumption because there is no internal buffer to drive.

5. Power-On Reset Circuitry.
