TECHNICAL NOTES 1. It is recommended that these converters be operated with local supply bypass capacitors of 1μF (tantalum type) at the +15V, –15V and +5V supply pins. The capacitors should be connected as close to the pins as possible. In high RFI noise environments, these capacitors should be shunted with 0.01μF ceramic capacitors. 2. The analog, digital and power grounds should be separated from each other as close as possible to pin 21 where they all must come together. 3. The “load” control pin is a level-triggered input which causes the register to hold data with a high input and transfer data to the DAC with a low input. 4. A setup time of 40ns minimum must be allowed for the input data. The DAC output voltage begins to change when the register output changes. 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. Unipolar Operation 1. Offset Adjustment. Set the input digital code to 1111 1111 1111 and adjust the Offset ADJ. potentiometer to give 0.0000V output. 2. Gain Adjustment. Set the input digital code to 0000 0000 0000 (straight binary) and adjust the GAIN ADJ. potentiometer to give the full-scale output voltage shown in Table 1. Bipolar Operation 1. Offset Adjustment. Set the digital input code to 1111 1111 1111 (offset binary) or 0111 1111 1111 (two’s complement) and adjust the OFFSET ADJ. potentiometer to give the negative full-scale output voltage shown in Table 2. 2. Gain Adjustment. Set the digital input code to 0000 0000 0000 (offset binary) or 1000 0000 0000 two’s complement) and adjust the GAIN ADJ. potentiometer to give the positive full-scale output voltage shown in Table 2.
