ADI AD5064BRUZ-REEL7

The AD5024/AD5044/AD5064/AD5064-1 are low power, quad 12-/14-/16-bit buffered voltage output nanoDAC converters that offer relative accuracy specifications of 1 LSB INL and 1 LSB DNL with the AD5024/AD5044/AD5064 individual reference pin and the AD5064-1 common reference pin options. The AD5024/AD5044/AD5064/AD5064-1 can operate from a single 4.5 V to 5.5 V supply. The AD5024/AD5044/AD5064/AD5064-1 also offer a differential accuracy specification of ±1 LSB. The devices use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards. Integrated reference buffers and output amplifiers are also provided on-chip. The AD5024/AD5044/AD5064/AD5064-1 incorporate a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place to the device. The AD5024/AD5044/ AD5064/AD5064-1 contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in powerdown mode. Total unadjusted error for the devices is < 2 mV.
