¡¡¡¡The AD5062£¬ a member of ADI¡¯s nanoDAC family£¬ is a low power£¬ single 16-bit unbuffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply. The part offers a relative accuracy specification of ¡À1 LSB£¬ and operation is guaranteed monotonic with a ¡À1 LSB DNL specification. The part uses a versatile 3-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 AD5062 is supplied from an external VREF pin. A reference buffer is also provided on-chip. The part incorporates a poweron reset circuit that ensures the DAC output powers up to zero scale or mid-scale and remains there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the device to typically 300 nA 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 ¡¶0.8 mV. This part exhibits very low glitch on power-up.
