APPLICATIONS Process Control Data Acquisition Systems Portable Battery Powered Instruments Digital Gain and Offset Adjustment Programmable Voltage and Current Sources Programmable Attenuators AD5062/AD5063 AD5062 8 Ld Sot23. The AD5062/AD5063, a member of the nanoDACTM family, are single 16-bit unbuffered voltage out DACs that operate from a single 2.7-5V supply. The AD5062 version is available in a 8 ld Sot23. The AD5063 version is available with on board resistors in a 10 ld uSOIC, making it easy to generate bipolar signals on the output. The parts utilize a versatile three-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 AD5062/AD5063 is supplied from an external REF pin. A reference buffer is also provided on chip. The part incorporates a power-on-reset circuit that ensures that the DAC output powers up to zero volts/ mid 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 50nA 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
