The AD5040/AD5060, members of the nanoDACTM 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
