The are complete and self-contained with a precision internal reference and fast output operational amplifi er. Pin programmable output voltage and current ranges are provided for a high degree of application fl exibility; the binary versions offer output voltage ranges and two current ranges while the BCD models offer and output ranges, respectively. The contains a precision embedded Zener reference circuit. This eliminates codedependent ground currents by routing current from the positive supply to the internal ground node as determined by the R-R ladder network. The internal feedback resistors for the on-board amplifi er track the ladder network resistors, enhancing temperature performance. The excellent tracking of the resistors results in temperature coeffi cients for differential nonlinearity, zero and gain of ±, ± and ±0ppm/ C maximum, respectively.

Volts Output Current, Pin ±0 ma Lead Temperature (soldering, s) 00 C TECHNICAL NOTES. The converters are designed and factory calibrated to give ±/LSB linearity (binary version) and ±/LSB linearity (BCD version) with respect to a straight line between end points. This means that if zero and full scale are exactly adjusted externally, the relative accuracy will be ±/LSB (±/LSB, BCD version) everywhere over the full output range without any additional adjustments.. These converters must be operated with local supply bypass capacitors from to ground and to ground. Tantalum type capacitors of are recommended and should be mounted as close as possible to the converter. If the converters are used in a high-frequency noise environment, a 0.0 ceramic capacitor should be used across each tantalum capacitor.. When operating in the current output mode, the equivalent internal current source of ma (.ma, BCD) must drive both the internal source resistances and the external load resistor. A 00ns output settling time is achieved for the voltage across a 0Ω load resistor; for higher value resistors the settling time becomes longer due to the output capacitance of the converter. For fastest possible voltage output for a large transition, an external fast-settling amplifi er such as DATEL s AM-00 should be used in the inverting mode. Settling time of less than μs can be achieved. See application diagram. CALIBRATION PROCEDURE Select the desired output voltage range and connect the converter as shown in the Output Range Selection Table and the Connection Diagrams. Refer to the Coding Tables.. Select the desired output range and connect the converter as shown in the Output Range Selection tables and the connection diagrams.. To calibrate, refer to the coding tables. Note that complementary coding is used.. Zero and Offset Adjustments. For unipolar operation set all digital inputs to "" (+.0 to +.V) and adjust the potentiometer for zero output voltage or current. For bipolar operation set all digital inputs to "" and adjust the OFFSET ADJUST potentiometer for the negative full scale (for voltage out) or positive full scale (for current out) output value shown in the coding table.. Gain Adjustment. Set all digital inputs to "0" (0V to +0.V) and adjust the potentiometer for the positive full scale (for voltage out) or negative full scale (for current out) output value shown in the coding table.
