AD5066:  Fully Accurate, Quad, 16-Bit, UnBuffered VOUT, 2.7 V to 5.5 V nanoDAC® with SPI Interface

Product Details


The AD5066 is a low power, 16-bit quad-channel, unbuffered voltage output nanoDAC® offering relative accuracy specifica-tions of ±1 LSB INL with individual reference pins and can operate from a single 2.7 V to 5.5 V supply. The AD5066 also offers a differential accuracy specification of ±1 LSB DNL. Reference buffers are also provided on-chip. The part uses a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and most DSP interface standards. The AD5066 incorporates a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write to the device takes place.

Total unadjusted error for the part is <0.8 mV. Zero code error for the part is 0.05 mV typically.

The AD5066 contains a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in power-down mode.

The outputs of all DACs can be updated simultaneously using the hardware LDAC function, with the added functionality of user software selectable DAC channels to update simultaneously. There is also an asynchronous CLR that clears all DACs to a software-selectable code—0 V, midscale, or full scale.

Product Highlights
