The DAC output range extends SCLK 8 DIN 10 SERIAL INPUT REGISITER from 0 V to V . REF 12 The DAC output range extends from 0 V to V and is guaranteed REF DGND monotonic, providing 1 LSB INL accuracy at 16 bits without Figure 2. AD5542 adjustment over the full specified temperature range of 40C to Table 1. +85C. Offering unbuffered outputs, the AD5541/AD5542 Part No. Description achieve a 1 s settling time with low power consumption and low AD5541A/AD5542A Single, 16-bit unbuffered nanoDAC, offset errors. Providing a low noise performance of 11.8 nV/Hz 1 LSB INL, LFCSP and low glitch, the AD5541/AD5542 is suitable for deployment Quad 12-/14-/16-bit nanoDAC, AD5024/AD5044/AD5064 across multiple end systems. 1 LSB INL, TSSOP AD5062 Single, 16-bit nanoDAC, 1 LSB INL, The AD5542 can be operated in bipolar mode, which generates SOT-23 a V output swing. The AD5542 also includes Kelvin sense REF AD5063 Single, 16-bit nanoDAC, 1 LSB INL, connections for the reference and analog ground pins to reduce SOT-23 layout sensitivity. PRODUCT HIGHLIGHTS The AD5541/AD5542 utilize a versatile 3-wire interface that is 1. Single-Supply Operation. The AD5541 and AD5542 are fully compatible with SPI, QSPI, MICROWIRE and DSP interface specified and guaranteed for a single 2.7 V to 5.5 V supply. standards. The AD5541/AD5542 are available in 8-lead and 2. Low Power Consumption. These parts consume typically 14-lead SOIC packages. 0.625 mW with a 5 V supply and 0.375 mV at 3 V. 3. 3-Wire Serial Interface. 4. Unbuffered Output Capable of Driving 60 k Loads. This reduces power consumption because there is no internal buffer to drive. 5. Power-On Reset Circuitry. Rev. F Information furnished by Analog Devices is believed to be accurate and reliable.
