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

I-toV precision amplifier.

T he AD5424/AD5433/AD5445 are CMOS 8, 10 and

12-bit current output digital-to-analog converters (DACs)

respectively.

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 AD5424 is available in small 20 lead CSP and 16

lead T SSOP packages, while the AD5433/AD5445 DACs

are available in small 20-lead CSP and T SSOP packages.

T hese DACs utilize Data readback allowing the user to

read the contents of the DAC register via the DB pins. On

power-up, the internal register and latches are filled with

zeros and the DAC outputs are at zero scale.

1. 10M H z M ultiplying Bandwidth

As a result of manufacture on a CMOS sub micron

process, they offer excellent four quadrant multiplication

characteristics, with large signal multiplying bandwidths

of up to 10MHz.

2. 4mm x 4mm Chip Scale Packages and small

T SSOP packages.

3. Low Voltage, Low Power Current Output DACs.
