GENERAL DESCRIPTION

The AD5062/AD5063, a member of the nanoDAC

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 <1mV.

These parts also provide a very low glitch on power-up.
