The AD5061, a member of the Analog Devices, Inc.,nanoDAC®family, is a low power, single 16-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply. The device offers a relative accuracy specification of ±4 LSB and operation is guaranteed monotonic with a ±1 LSB DNL specification. The device 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 AD5061 is supplied from an external VREFpin. A reference buffer is also provided on-chip. The device incorporates a power-on reset circuit that ensures the DAC output powers up to mid-scale or zero scale and remains there until a valid write takes place to the device. The device contains a power-down feature that reduces the current consumption of the device to typically 330 nA at 5 V and provides software-selectable output loads while in power-down mode. The device is put into power-down mode over the serial interface. Total unadjusted error for the device is <3 mV. This device exhibits very low glitch on power-up.PRODUCT HIGHLIGHTSAvailable in a small 8-lead SOT-23 package.16-bit resolution, 4 LSB INL.Low glitch on power-up.High speed serial interface with clock speeds up to 30 MHz.Three power-down modes available to the user.Reset to known output voltage (midscale or zero scale).APPLICATIONSProcess controlData acquisition systemsPortable battery-powered instrumentsDigital gain and offset adjustmentProgrammable voltage and current sourcesProgrammable attenuators
