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 (AD5542A) or −40°C to +125°C (AD5512A). Offering unbuffered outputs, the AD5512A/AD5542A achieve a 1 μs settling time with low offset errors ideal for high speed open loop control. The AD5512A/AD5542A incorporate a bipolar mode of operation that generates a ±VREF output swing. The AD5512A/AD5542A also include Kelvin sense connections for the reference and analog ground pins to reduce layout sensitivity. The AD5512A/AD5542A are available in a 16-lead LFCSP with the AD5542A also available in a 10-lead LFCSP and a 16-lead TSSOP. The AD5512A/AD5542A use a versatile 3-wire interface that is compatible with 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface standards.
