GENERAL DESCRIPTION
The AD5040/AD5060, members of the nanoDAC
TM
family,
are single 14/16-bit buffered voltage out DACs. Both parts are
available in a 8ld Sot23. The AD5040 can be operated from
2.7-5.5V and the AD5060 can be operated at 3V/5V.
The part utilizes a versatile three-wire serial interface that
operates at clock rates up to 30 MHz and is compatible with
standard SPITM, QSPITM, MICROWIRETM and DSP interface
standards.
The reference for the AD5040/AD5060 is supplied from an
external REF pin. A reference buffer is also provided on chip.
The parts incorporate 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 parts also
contain 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.
