GENERAL DESCRIPTION
The AD5062, a member of ADI’s nanoDAC family, is a low power, single 16-bit unbuffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply. The part offers a relative accuracy specification of ±1 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 AD5062 is supplied from an external VREF pin. A reference buffer is also provided on-chip. The part incorporates a poweron reset circuit that ensures the DAC output powers up to zero scale or mid-scale and remains there until a valid write takes place to the device.
