AD5062

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 ±1 LSB, and operation is guaranteed monotonic with a ±1 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 V_REF pin. A reference buffer is also provided on-chip. The part incorporates a power-on 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.
