GENERAL DESCRIPTION
The AD5641, a member of the
nano
DAC family, is a single,
14-bit, buffered, voltage out DAC that operates from a single
2.7 V to 5.5 V supply, consuming <100 μA at 5 V. The part
comes in a tiny SC70 package. Its on-chip precision output
amplifier allows rail-to-rail output swing to be achieved. The
AD5641 utilizes a versatile 3-wire serial interface that operates
at clock rates up to 30 MHz and is compatible with SPI, QSPI,
MICROWIRE, and DSP interface standards. The reference for
AD5641 is derived from the power supply inputs and, therefore,
gives the widest dynamic output range. The part incorporates a
power-on reset circuit, which ensures that the DAC output
powers up to 0 V and remains there until a valid write to the
device takes place.
