Nano DAC™

Process control Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources

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

The AD5066 is a low power, 16-bit quad-channel, unbuffered voltage output nanoDAC® offering relative accuracy specifications 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.
