8 / 12 page AD660 REV. A –8– Figure 5 shows the AD660 using the AD586 precision 5 V refer- ence in the bipolar configuration. The highest grade AD586MN is specified with a drift of 2 ppm/ °C which is a 7.5× improve- ment over the AD660’s internal reference. This circuit includes two optional potentiometers and one optional resistor that can be used to adjust the gain, offset and bipolar zero errors in a manner similar to that described in the BIPOLAR CONFIGU- RATION section. Use –5.000000 V and +4.999847 as the out- put values. The AD660 can also be used with the AD587 10 V reference, using the same configuration shown in Figure 5 to produce a ±10 V output. The highest grade AD587LR, N is specified at 5 ppm/ °C, which is a 3× improvement over the AD660’s inter- nal reference. Figure 6 shows the AD660 using the AD680 precision ±10 V reference, in the unipolar configuration. The highest grade AD688BQ is specified with a temperature coefficient of 1.5 ppm/ °C. The ±10 V output is also ideal for providing pre- cise biasing for the offset trim resistor R4. 16-BIT LATCH 16-BIT DAC CONTROL LOGIC +10V REF 16-BIT LATCH 20 24 22 21 5 11 12 16 15 14 13 17 18 19 23 AD660 10k 10.05k 10k HBE LBE CS SIN/ DB0 MSB/LSB/ DB1 DB7 S OUT SPAN/ BIP OFF V OUT AGND REF OUT REF IN LDAC CLR SER DGND –V EE +V CC +V LL 1 2 3 4 OUTPUT R2 50 Ω 5 6 4 2 AD586 GND TRIM V OUT +V CC R2 10k Ω R1 100 Ω UNI/BIP CLR/ Figure 5.
