2.7 V to 5.5 V, Serial-Input, Voltage-Output, 16-Bit DAC in 10-lead LFCSP, 16-lead 3 mm x 3 mm LFCSP, and 16-lead TSSOP

The AD5512A / AD5542A are single, 12-/16-bit, serial input, unbuffered voltage output digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply. 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.
