GENERAL DESCRIPTION

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 VREFand 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.
