Single 16-bit digital-to-analog converter (DAC), 4 LSB INL Power-on reset to midscale or zero-scale Guaranteed monotonic by design Low power serial interface with Schmitt-triggered inputs Small 8-lead SOT-23 package, low power

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 part offers a relative accuracy specification of ±4 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 AD5061 is supplied from an external V REF pin. A reference buffer is also provided on-chip. The part incorporates a poweron reset circuit that ensures the DAC output powers up to midscale or zero 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 330 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 <3 mV. This part exhibits very low glitch on power-up. ™
