GENERAL DESCRIPTION
The AD5541A/AD5542A/AD5512A1 are single, 16-/16-/12-bit,
serial input, unbuffered voltage output digital-to-analog conver
ters (DACs) that operate from a single 2.7 V to 5.5 V supply.
The AD5541A/AD5542A/AD5512A utilize a versatile 3-wire
interface that is compatible with a 50 MHz SPI, QSPI™,
MICROWIRE™, and DSP interface standards.
These DACs provide 16-/12-bit performance without any adjust
ments. The DAC output is unbuffered, which reduces power
consumption and offset errors contributed to by an output buffer.
The AD5542A/AD5512A can be operated in bipolar mode, which
generates a ±VREF output swing. The AD5542A/AD5512A also
includes Kelvin sense connections for the reference and analog
ground pins to reduce layout sensitivity.
The AD5541A is available in 10-lead 3 mm × 3 mm LFCSP and
10-lead MSSOP. The AD5541A-1 is available in 8-lead 3 mm ×
3 mm LFCSP. The AD5542A/AD5512A are available in 16-lead
3 mm × 3 mm LFCSP and the AD5542A is also available in
16-lead TSSOP. The AD5542A-1 is available in 10-lead LFCSP.
The AD5541A and AD5542A are specified over a temperature
