T he AD 5450/AD 5451/AD 5452/AD 5453 are C M OS 8,

10, 12 and 14-bit Current Output digital-to-analog

converters respectively.

T he applied external reference input voltage (V_REF

)

determines the full scale output current. An integrated

feedback resistor (R_FB) provides temperature tracking and

full scale voltage output when combined with an external

Current to Voltage precision amplifier.

T hese devices operate from a +2.5 V to 5.5 V power sup-

ply, making them suited to battery powered applications

and many other applications.

T he AD 5450/AD 5451/AD 5452/AD 5453 D AC s are

available in small 8-lead T SOT & MSOP packages.

T hese DACs utilize double buffered 3-wire serial interface

that is compatible with SPI^{T M}, QSPI^{T M}, MICROWIRE^{T M}

and most DSP interface standards.

On power-up, the internal shift register and latches are

filled with zeros and the DAC output is at zero scale.

As a result of manufacture on a CMOS sub micron

process, they offer excellent four quadrant multiplication

characteristics, with large signal multiplying bandwidths

of 10M H z.
