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 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.
