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  
AD5512A/AD5542A also include Kelvin sense connections for  
the reference and analog ground pins to reduce layout sensitivity.

PRODUCT HIGHLIGHTS  
1. 16-bit performance without adjustment.  
2. 2.7 V to 5.5 V single supply operation.  
3. Low 11.8 nV/√Hz noise spectral density.  
4. Low 0.05 ppm/°C temperature drift.  
5. 3 mm × 3 mm LFCSP and TSSOP packaging.  
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.
