AD5066

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

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

  1. Quad channel available in 16-lead TSSOP, ±1 LSB INL.
  2. Individual voltage reference pins
  3. 16 bit accurate, 1 LSB INL.
  4. TUE = ±0.8 mV max and zero code error = 0.1 mV max.
  5. High speed serial interface with clock speeds up to 50 MHz.
  6. Three power-down modes available to the user.
  7. Reset to known output voltage (zero scale or midscale).

Most Helpful Review

AD5066 performs great. I could not measure how precise its 16-bits are, but at least I could not notice any deviation in the circuit we are carrying on. Four outputs with individual reference voltages and SPI-input makes it an ideal DAC. On the other hand I must point out its only disadvantage. For AD5066 it is compulsory to send 4 bytes in arrow without breaking the SPI transmission. This drawback makes my data bus to hold all other transmissions and guarantee that the 32-bit transmission has been completed successfully. This took me sometime to achieve, since it required advanced synchronization. Since only 16 out of the 32 bits sent every time are used, I also feel there is some time wasting during transmission. Improving transmission to sending only the 16 bits needed would be a great enhance.
