GENERAL DESCRIPTION
The AD5040 and the AD5060, members of the ADI nanoDAC family, are low power, single 14-/16-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply. The AD5040/AD5060 parts offer a relative accuracy specification of ±1 LSB and operation are guaranteed monotonic with a ±1 LSB DNL specification. The parts use 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 both the AD5040 and AD5060 is supplied from an external VREF pin. A reference buffer is also provided on-chip. The AD5060 incorporates a power-on 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 AD5040 and the AD5060 both contain a po...
