在SOT-23完全準(zhǔn)確的14/16位VOUT nanoDAC SPI接口的2.7V至5.5V的AD5040/AD5060數(shù)據(jù)表

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 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 parts are put into power-down mode over the serial interface. Total unadjusted error for the parts is <2 mV. Both parts exhibit very low glitch on power-up.
