DESCRIPTION

The DAC9331-14 is a low cost 14-bit multiplying digital-to-analog converter packaged in a unique 24-pin double DIP. Capable of 2 and 4-quadrant multiplication, the unit is TTL/DTL and CM OS com- patible with power consumption less than 30mW . Power supply options include +5V (-1) or + 15V (-2). Outstanding features of the DAC9331-14 include: True 14-bit performance — Up to 14-bit resolution and accuracy over the 0˚to 70˚C operating range. 2 and 4-quadrant multiplication — Reference input range to ±25 volts. Low pow er — CM OS technology provides less than 30mW total power dissipation — a real battery saver. Reliability plus — Packaged in a unique enclosure t h at has undergone extensive environmental testing during its development. The DAC9331-14 is continuously monitored during all assembly and test operations by our quality control organization. Reliability is enhanced by batch-processed, preci- sion laser-trimmed resistor networks fabricated in our own facility. Similar to monoli thic circuits, the networks are processed and functionally trimmed to assure consistent performance.

The switching threshold is typically VDD/2 for –1 models and VDD/6 for –2 models. The logic input must never exceed VDD/3 (or –2 models. 2. Using internal feedback resistor. 3. Using the internal Ffeedback with nulled external amplifier in a constant 25ºC ambient. (Offset doubles every 10ºC). 4. Best straight line method of test. 5. The DAC9331-14 Series is designed to be used only in those applications where the current output is virtual ground: i.e., the summing junction of an op amp in the inverting mode. The internal feedback resistor (R feedback) must be used to achieve temperature tracking. See APPLICATIONS INFORM ATION for recommended circuit configurations. 6. The power supply voltage must not exceed +10V for the –1 versions or +15.5V for the –2 versions.
