AD5512A: 2.7 V to 5.5 V, Seri

AD5512A:  2.7 V to 5.5 V, Serial-Input, Voltage-Output

 

The AD5541A/AD5542A/AD5512A are single, 16-/16-/12-bit, serial input, unbuffered voltage output digital-to-analog converters (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 adjustments. 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 range of −40°C to 105°C.
