Description

The AD5040/AD5060, members of the nanoDAC^TM family, are single 14/16-bit buffered voltage out DACs. Both parts are available in a 8ld Sot23. The AD5040 can be operated from  2.7-5.5V and the AD5060 can be operated at 3V/5V.  The part utilizes a versatile three-wire serial interface that  operates at clock rates up to 30 MHz and  is compatible with  standard SPI™, QSPI™, MICROWIRE™ and DSP interface  standards. 

The reference for the AD5040/AD5060 is supplied from an external REF pin. A reference buffer is also provided on chip.  The parts incorporate a power-on-reset circuit that ensures that  the DAC output powers up to zero volts/ mid scale and remains  there until a valid write takes place to the device. The parts also  contain a power-down feature that reduces the current  consumption of the device to 50nA at 5 V and provides  software selectable output loads while in power-down mode.  The part is put into power-down mode over the serial interface.  Total unadjusted error for the part is <1mV.  These parts also provide a very low glitch on power-up.
