The 7846A has V REF+ and V REF- reference inputs and an on-chip output amplifier which gives the option of unipolar or bipolar output. The 7846A uses a segmented architecture. The 4 MSBs in the DAC latch select one of the segments in a 16-resistor string. Both taps of the segment are buffered by amplifiers and fed to a 12-bit DAC, which provides a further 12 bits of resolution. This archi- tecture ensures 16-bit monotonicity. Excellent integral linearity results from tight matching between the input offset voltages of the two buffer amplifiers. In addition to the excellent accu- racy specifications, the 7846A also offers a comprehensive microprocessor interface. There are 16 data I/O pins, plus control lines (CS, R/W, LDAC and CLR). R/W and CS have readback function which allows writing to and reading from the I/O latch. Maxwell Technologies' patented RAD-PAK® packaging technol- ogy incorporates radiation shielding in the microcircuit pack- age. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S. 16 Segment Switch Matrix Control Logic A2 A1 A3 I/O Latch DAC Latch 12-bit DAC - + - + - + R R 6 5 23 22 25 24 20 3 10 9 8 7 21 4 V DD V CC V REF+ V REF- V SS DB15 DB0 DGND CLR LDAC R/W CS V OUT R IN 12 12 4 R R R Logic Diagram 7846A |
