The 8 LSBs, the 4 MSBs, and 5 control bits are written using three different addresses. Developed for a wide range of supply voltages, the TLV5633 can be operated from 2.7 V to 5.5 V. The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. The buffer features a Class A (slow mode: AB) output stage to improve stability and reduce settling time. The programmable settling time of the DAC allows the designer to optimize speed versus power dissipation. With its on-chip prog...
